## PAN-308507

Strata Logging Service (SLS) log-forwarding streams intermittently show as inactive. When checking the status of log-forwarding connections, one or more streams are reported as inactive. Restarting the log-receiver process temporarily resolves the issue, but the streams become inactive again after approximately 1-2 hours. This intermittent inactivity results in log loss.

```

After you disable the shared optimization feature in Panorama, ensure that you perform a full configuration push to all managed multi-vsys devices to re-establish a baseline. Failure to include every device group associated with the multi-vsys device during this push may result in incomplete or inconsistent configurations across virtual systems.

## PAN-303959

```caveat
This issue is now resolved. See PAN-OS 11.2.11 Addressed Issues, PAN-OS 11.2.7-h10 Addressed Issues and PAN-OS 11.2.10-h3 Addressed Issues
```

Traffic that is incorrectly identified as unknown-tcp/unknown-udp eventually drops due to an App-ID resource limitation issue.

## PAN-301801

```caveat

On Log Collectors, the Elasticsearch process might fluctuate between green and red states, causing log collection interruptions. This issue occurs when the number of shards exceeds the supported threshold of 1,000 shards per Elasticsearch instance.

## PAN-298505

```caveat
This issue is now resolved. See PAN-OS 11.2.7-h4 Addressed Issuesand PAN-OS 11.2.10 Addressed Issues
```

After upgrading multi-vsys firewalls, the sequence of the virtual system IDs (vsys ID) changes causing auto-commit failures with validation errors. This occurs when the multi-vsys firewall has virtual systems managed by Panorama, and the vsys ID sequence breaks when unused virtual systems are deleted and the changes are pushed to the firewall.

## PAN-297295

```caveat
VM-Series firewalls on Microsoft Azure environments only
```

After upgrading to an affected release, the firewall restarts continuously because the **brdagent** process restarts multiple times and exhausts its restart limit, resulting in a segfault error. This issue occurs when a high burst of traffic is sent to the Azure PA-VM (Palo Alto Networks Virtual Machine), and impacts production environments due to the regular reboots.

**Workaround**: Migrate the VM instance to Dv5 instance type. On these instance types, SYN packets are not routed to the synthetic path, avoiding this condition. Suggested direct resizing paths are:

- D3_v2/DS3_v2 to D8ds_v5
- D4_v2/DS4_v2 to D8ds_v5
- D5_v2/DS5_v2 to D16ds_v5

Azure VMs with ephemeral storage can only be resized to another type with ephemeral storage.

## PAN-296752

```caveat
This issue is now resolved. See PAN-OS 11.2.10 Addressed Issues
```

The PA-1410 firewalls experience a spike in the management plane CPU utilization when the monitor-dp process attempts to retrieve the power cycle count from the NVMe drive’s SMART data. This condition leads to repeated reboots of the device, requiring a hard reset for recovery.

## PAN-295803

```caveat
This issue is now resolved. See PAN-OS 11.2.11 Addressed Issues, PAN-OS 11.2.7-h10 Addressed Issues and PAN-OS 11.2.10-h3 Addressed Issues
```

A configd memory leak occurs post commit (during Panorama connectivity check), potentially leading to OOM (out of memory condition) and device reboot.

## PAN-294179

```caveat
This issue is now resolved. See PAN-OS 11.2.11 Addressed Issues and PAN-OS 11.2.7-h3 Addressed Issues.
```

On the**Panorama Config Audit** page, some commit versions might display incorrect or missing data. Fields such as, **COMMITTED BY**, **COMMIT DATE**, and**OBJECT CHANGES** might not be visible for some commit versions. Sometimes, commit versions can disappear after a refresh and the commit description field might display corrupted characters.

## PAN-292202

```caveat
This issue is now resolved. See PAN-OS 11.2.7-h3 Addressed Issues.
```

The system logs repeatedly displayed the alert `Clearing snmpd.log due to log overflow` due to the SNMP counters rolling over. This is a benign message and does not impact device functionality.

## PAN-291716

(PA-460 firewalls only) The firewall experiences an out-of-memory (OOM) condition and displays an error message. This issue causes the device to crash and reboot unexpectedly.

## PAN-291661

```caveat
This issue is now resolved. See PAN-OS 11.2.10 Addressed Issues
```

Upon upgrade, the ElasticSearch health status intermittently transitions to the Red status for sometime, and then auto-recovers back to Green. During the Red status periods, the cluster logs are unavailable. This occurs due to disk write operations being excessively slow, failing to meet the minimum time threshold required to save the cluster state.

## PAN-291288

```caveat
This issue is now resolved. See PAN-OS 11.2.8 Addressed Issuesand PAN-OS 11.2.7-h3 Addressed Issues
```

An active firewall might unexpectedly reboot due to a pan_task crash caused by a page allocation failure. This issue is observed after a period of runtime with traffic and telemetry collection.

## PAN-290449

```caveat
This issue is now resolved. See PAN-OS 11.2.8 Addressed Issuesand PAN-OS 11.2.7-h3 Addressed Issues
```

The scheduled vulnerability reports that are configured to be sent via email with multiple attachments send the first attached report only. The remaining attachments are dropped.

## PAN-290088

When pushing configurations from Panorama to a firewall, a memory leak might occur in the firewall's configd process, particularly when the configurations contain shared policies. Each configuration push causes the configd process to consume additional memory that is not released after the commit completes.

## PAN-289383

```caveat
PA-800 series firewalls only
```

Upgrading firewalls to PAN-OS 11.0 or later causes SFP ports to go non-operational when the firewall uses forced port mode and the connected peer device operates without auto-negotiation.

**Workaround:** Enable auto-negotiation on the connected peer firewall.

## PAN-287803

After upgrading to PAN-OS 11.1.6-h4, users might be unable to access some URLs due to issues involving the accumulation proxy and the Path Maximum Transmission Unit (MTU).

To address this issue, use one of the following workarounds:

- Configure the **Adjust TCP MSS** option for the egress interface to the unreachable server. The amount to adjust the maximum segment size depends on the path to the server.
- Disable the accumulation proxy using the `debug dataplane set ssl-decrypt accumulate-client-hello disable yes` CLI command.

## PAN-286848

```caveat
This issue is now resolved. See PAN-OS 11.2.7 Addressed Issues
```

ECMP incorrectly balances sessions across links based on the configured metric, which leads to an imbalance in traffic distribution and results in traffic assignment shifting disproportionately to routes with lower metrics.

## PAN-286231

```caveat
This issue is now resolved. See PAN-OS 11.2.7-h3 Addressed Issues.
```

When performing a partial **Commit and Push** on Panorama, there is a risk that unintended configuration changes might be pushed to a firewall.

This issue is more likely to occur in the following scenarios:

- When you run **Commit and Push** operations as a single action.
- When you trigger multiple parallel commit-all jobs at the same time.
- Device groups and templates have different configuration synchronization versions.

**Workaround:** Perform one of the following steps:

- Perform commit and push as two separate, sequential steps.
- Perform a full push instead of selective push.

## PAN-285894

```caveat
This issue is now resolved. See PAN-OS 11.2.7 Addressed Issues
```

If the Preserve Pre-NAT feature is enabled, dataplane crashes may occur, which could result in firewall reboots.

**Workaround:** Disable the Preserve Pre-NAT feature using the `set deviceconfig setting preserve-prenat-feature no` CLI command.

## PAN-285587

Bootstrapping the VM-Series firewall on OpenStack with user-data does not function correctly. When you run the command show system bootstrap status shows, the output shows the message No Install media detected.

## PAN-284067

```caveat
This issue is now resolved. See PAN-OS 11.2.8 Addressed Issues
```

A cumulative memory leak in the devsrvr process gets progressively worse whenever the CLI command `show running application statistics` is issued. This memory leak will gradually consume system memory and produce an out-of-memory (OOM) condition, leading to an eventual firewall reboot.

## PAN-283467

```caveat
PA-3400 Series firewalls only
```

The firewall might unexpectedly reboot and enter maintenance mode due to a ctd-agent out-of-memory (OOM) condition when undergoing advanced services load testing with a high volume of IoT EAL log forwarding.

**Workaround:** Limit the number of EAL logs generated by the firewall using the following CLI command: `debug iot eal key-value EAL_PENDING_BYTES=1000`.

## PAN-283429

When you use custom certificates for the connection between Panorama and a log collector, the automated renewal for the predefined ElasticSearch certificates gets disrupted.

**Workaround**: Remove the custom certificates before the ElasticSearch certificates expire. This allows the system to correctly identify and renew the predefined ElasticSearch certificates. After the renewal is complete, re-install the custom certificates.

## PAN-282277

```caveat
PA-3260 firewalls only
```

An interface unexpectedly moves out of Link Aggregation Control Protocol (LACP), which causes an out-of-memory (OOM) condition on the *logrcvr* process, resulting in the interface going down and then automatically coming back up without intervention.

## PAN-281885

When exporting and importing the CSV file, the hash values of pre-shared key (PSK) variables set at template and template stack levels inconsistently change, resulting in both variables displaying the same hash value.

## PAN-280471

When applying filters or searching for logs in the **Panorama** > **Monitor** > **Logs**section, you might experience slow performance.

## PAN-279901

```caveat
This issue is now resolved. See PAN-OS 11.2.7-h1 Addressed Issues
```

When decryption is enabled, segmented Client Hello packets can cause website access issues and memory leaks under the following conditions:

- The segmented Client Hello packets arrive out-of-order
- The segmented Client Hello packets arrive out-of-order and can be reassembled into a complete Client Hello when the first contiguous segment is formed by NGFW
- The first segment of the Client Hello packets is less than 5 bytes
- A decryption policy rule excludes this traffic from decryption and a Security policy rule (URL filtering) denies this session

## PAN-279746

An SSL/TLS Client Hello may not be transmitted out of the firewall if the Client Hello arrives in multiple TCP segments and the traffic is not subject to SSL decryption (for example, SMTP over SSL).

## PAN-279621

```caveat
This issue is now resolved. See PAN-OS 11.2.6 Addressed Issues
```

Early aging and removal of firewall session while they are still active can lead to intermittent instabilities and crashes for proxy traffic, the Content and Threat detection engine, and any data-path processing.

## PAN-279415

```caveat
This issue is now resolved. See PAN-OS 11.2.8 Addressed Issues
```

Service routes configured for a data plane interface might incorrectly route traffic through the management plane interface instead. This issue impacts Syslog and CRL status traffic when the service route lacks a specific destination custom service route.

## PAN-276920

URL filtering response pages may load slowly or fail to display when users request websites that are blocked in the URL Filtering profile (site access for the corresponding URL category is **block**, **continue**, or **override**) attached to the matching Security policy rule. This occurs on an intermittent basis.

## PAN-277034

```caveat
This issue is now resolved. See PAN-OS 11.2.7-h3 Addressed Issues

When Panorama is not internet-connected and you try to upload images to the managed firewalls by using the **Validate** option, the upload fails with the following error: `Failed to create multi-upload job. No valid software deploy targets found.`

## PAN-275047

```caveat
VM-Series firewalls only
```

After an upgrade, the firewall is unable to send logs to the Strata Logging Service (SLS) when using a specific proxy server, and the SSL connection status displays as failed when attempting to forward logs through the web proxy.

## PAN-274314

```caveat
PA-1400 Series firewalls, PA-3400 Series firewalls, and PA-5400 Series firewalls only
```

When the pan_task process restarts, control plane packets are dropped, which can impact LACP and pings to host interfaces.

## PAN-271913

Firewalls in HA configurations were experiencing consistent memory leaks on the active firewall, leading unexpected failovers while using Cloud Identity Engine (CIE).

## PAN-261429

```caveat

When the DHCP server is enabled for GlobalProtect, the commit error message is not properly displayed when **Any** is selected as the source interface in the service router configuration ( **Device** > **Setup** > **Service** > **Service Router Configuration**).

## PAN-259423

When the GlobalProtect DHCP feature is enabled with two primary DHCP servers on the GlobalProtect gateway, the gpsvc gets stuck during renewal and after HA failover.

## PAN-254236

TLSv1.3 hybridized Kyber support in the latest versions of Chrome and Edge browsers results in dropped Client Hello packets when SSL/TLS handshake inspection is enabled.

**Workaround:** Disable [SSL/TLS handshake inspection](https://docs.paloaltonetworks.com/advanced-url-filtering/administration/url-filtering-features/inspect-ssl-tls-handshakes).

## PAN-254108

when upgrading or downgrading a Panorama management server (**Panorama** > **Software**), managed device (**Panorama** > **Device Deployment** > **Software**), or standalone firewall (**Device** > **Software**), **Base Releases** and **Preferred Releases** settings are checked (enabled) by default and cause no PAN-OS software images to display.

**Workaround:** Uncheck (disable) **Base Releases** or **Preferred Releases** to display either the available base PAN-OS or preferred PAN-OS releases available to download and install.

## PAN-253963

The auto commit job may take longer than expected to complete when the Panorama management server is in Panorama or Log Collector mode.

## PAN-252661

If you change the service route of gp-ip-mgmt in **Device > Setup > Services > Service Features > gp-ip-mgmt** and **Commit**, the change won’t take effect. gp-ip-mgmt continues to use the last committed service route.

**Workaround:** After you change the service route interface for gp-ip-mgmt, navigate to either a GlobalProtect portal or gateway, click **OK**to save the configuration, and **Commit**the changes. This commit will include the service route change.

## PAN-250246

Panorama and the firewall display inconsistent IP addresses for dynamic address group members after manually syncing.

## PAN-250062

Device telemetry might fail at configured intervals due to bundle generation issues.

## PAN-248836

The Advanced DNS Security trial license and trial license information cannot be activated and viewed, respectively, on a managed firewall (with expired or active status) from Panorama. These tasks can only be performed on the firewall.

## PAN-247728

When Advanced Routing is enabled, IP multicast is not supported. An upcoming version will provide support for this feature. Customers who have multicast configured or who plan to deploy multicast routing should not upgrade to 11.2.0. Additionally, when Advanced Routing is enabled, the BGP dampening configuration isn't applied to any peers or peer group; the configuration is preserved but has no effect on BGP. Customers can use BGP even if they have applied a Dampening profile to a specific set of peers. The issue doesn't affect any other BGP features.

## PAN-241994

The VMX hardware version was upgraded from vmx-10 to vmx-15 on ESXi and NSX-T. Support for vmx-15 is supported on ESXi 6.7 U2 and onwards. Palo Alto Networks recommends that you upgrade your ESXi version if it is less than 6.7 U2. For more information, see the [compatibility matrix](https://kb.vmware.com/s/article/2007240).

## PAN-239612

When the firewall is running PAN-OS 11.2.0 and Advanced Routing is enabled, DHCPv4 relay agent functions successfully, but DHCPv6 relay agent doesn't work.

## PAN-237106

LSVPN satellite certificates may be generated with serial numbers exceeding 40 hexadecimal characters. This causes certificate revocation and deletion operations to fail with the following error messages:

- `db-serialno can be at most 40 characters`
- `db-serialno is invalid`

**Workaround:**

To resolve this issue, use the following CLI commands with the LSVPN satellite serial number to manually delete or revoke the affected certificates:

**Delete certificate information**:`delete sslmgr-store certificate-info portal name <name> serialno <satellite_serial>`

**Revoke satellite certificates**:`delete sslmgr-store satellite-info-revoke-certificate portal <name> serialno <list_of_satellite_serials>`

## PAN-236649

If you change the configuration of a firewall acting as a PPPoEv4 or PPPoEv6 client, old routes from the Forwarding Information Base (FIB) and route table for an inherited configuration with dynamic-identifier or client remain visible. Old routes also remain visible for an inherited interface when you execute the CLI command, `show interface all`.

**Workaround:** Unconfigure and configure the Inherited Interface.

## PAN-234015

The X-Forwarded-For (XFF) value is not displayed in traffic logs.

## PAN-207442

For M-700 appliances in an active/passive high availability (**Panorama** > **High Availability**) configuration, the `active-primary` HA peer configuration sync to the `secondary-passive` HA peer may fail. When the config sync fails, the job Results is `Successful` (**Tasks**), however the sync status on the **Dashboard** displays as `Out of Sync` for both HA peers.

**Workaround**: Perform a local commit on the `active-primary` HA peer and then synchronize the HA configuration.

1. [Log in to the Panorama web interface](https://docs.paloaltonetworks.com/panorama/11-0/panorama-admin/set-up-panorama/access-and-navigate-panorama-management-interfaces/log-in-to-the-panorama-web-interface) of the `active-primary` HA peer.
2. Select **Commit** and **Commit to Panorama**.
3. In the `active-primary` HA peer **Dashboard**, click **Sync to Peer** in the High Availability widget.

## PAN-206909

The Dedicated Log Collector is unable to reconnect to the Panorama management server if the `configd` process crashes. This results in the Dedicated Log Collector losing connectivity to Panorama despite the managed collector connection `Status` (**Panorama** > **Managed Collector**) displaying `connected` and the managed colletor `Health` status displaying as healthy.

This results in the local Panorama config and system logs not being forwarded to the Dedicated Log Collector. Firewall log forwarding to the disconnected Dedicated Log Collector is not impacted.

**Workaround:** Restart the `mgmtsrvr` process on the Dedicated Log Collector.

1. [Log in to the Dedicated Log Collector CLI](https://docs.paloaltonetworks.com/panorama/11-0/panorama-admin/set-up-panorama/access-and-navigate-panorama-management-interfaces/log-in-to-the-panorama-cli).
2. Confirm the Dedicated Log Collector is disconnected from Panorama.
  `admin>``show panorama-status`
  Verify the `Connected` status is `no`.
3. Restart the `mgmtsrvr` process.
  `admin>``debug software restart process management-server`

In **Network** > **Interface** > **Ethernet**, the power over Ethernet (PoE) ports do not display a **Tag** value.

## PAN-196758

On the Panorama management server, pushing a configuration change to firewalls leveraging SD-WAN erroneously show the auto-provisioned BGP configurations for SD-WAN as being edited or deleted despite no edits or deletions being made when you **Preview Changes** (**Commit** > **Push to Devices** > **Edit Selections** or **Commit** > **Commit and Push** > **Edit Selections**).

## PAN-195968

```caveat
PA-1400 Series firewalls only
```

When using the CLI to configure power over Ethernet (PoE) on a non-PoE port, the CLI prints an error depending on whether an interface type was selected on the non-PoE port or not. If an interface type, such as tap, Layer 2, or virtual wire, was selected before PoE was configured, the error message will not include the interface name (eg. ethernet1/4). If an interface type was not selected before PoE was configured, the error message will include the interface name.

## PAN-187685

On the Panorama management server, the Template Status displays no synchronization status (**Panorama** > **Managed Devices** > **Summary**) after a bootstrapped firewall is successfully added to Panorama.

**Workaround:** After the bootstrapped firewall is successfully added to Panorama, [log in to the Panorama web interface](https://docs.paloaltonetworks.com/panorama/10-2/panorama-admin/set-up-panorama/access-and-navigate-panorama-management-interfaces/log-in-to-the-panorama-web-interface.html) and select **Commit** > **Push to Devices**.

## PAN-187407

The configured Advanced Threat Prevention inline cloud analysis action for a given model might not be honored under the following condition: If the firewall is set to **Hold client request for category lookup**and the action set to **Reset-Both** and the URL cache has been cleared, the first request for inline cloud analysis will be bypassed.

## PAN-184406

Using the CLI to add a RAID disk pair to an M-700 appliance causes the dmdb process to crash.

**Workaround:** Contact customer support to stop the dmdb process before adding a RAID disk pair to a M-700 appliance.

## PAN-183404

Static IP addresses are not recognized when "and" operators are used with IP CIDR range.

## PAN-181933

If you use multiple log forwarding cards (LFCs) on the PA-7000 series, all of the cards may not receive all of the updates and the mappings for the clients may become out of sync, which causes the firewall to not correctly populate the Source User column in the session logs.
