PAN-308564 | Packets are dropped on SD-WAN interfaces if they require fragmentation for an interface but have the Don't Fragment (DF) bit set. This results in unexpected packet drops. This affects client to server sessions when using SD-WAN for NGFW. Workaround: Allow fragmenting packets with DF bit set (debug dataplane set ip4-ignore-df yes).
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-304576 `This issue is now resolved. See PAN-OS 11.2.11 Addressed Issues` | Traffic interruption may occur when inspection of HTTP/2 traffic is enabled. Workaround: Disable HTTP/2 server push using the set deviceconfig setting http2 server-push no CLI command.
PAN-303959 `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 `This issue is now resolved. See` PAN-OS 11.2.11 Addressed Issues and PAN-OS 11.2.7-h8 Addressed Issues | On Log Collectors, the Elasticsearch process might fluctuate between green and red states, causing log collection interruptions.

`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-297775

The wrong vsys is referenced under Visible Virtual System after every local firewall commit (auto-commit, commit, content install) if the display name of the vsys matches another vsys ID (for example, the vsys2 display name is vsys1). The incorrect vsys reference causes inter-vsys routing to fail.
Workaround: Change the vsys display name so that it doesn't reference an existing vsys ID.

PAN-297610 `This issue is now resolved. See` PAN-OS 11.2.11 Addressed Issues and PAN-OS 11.2.7-h8 Addressed Issues. | A firewall may become unresponsive after an upgrade due to the fsck command scanning drive partitions in parallel with the root partition, causing the process to take an extended amount of time.

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

(`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 `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 `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
`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-293673 `This issue is now resolved. See` PAN-OS 11.2.7-h1 Addressed Issues. | When the firewall generates a high volume of logs and attempts to export these logs to an FTP server, it may consume excessive memory leading to all PAN-OS processes crashing.
PAN-292344 `This issue is now resolved. See` PAN-OS 11.2.8 Addressed Issues | Upgrading to an affected release causes the firewall to reboot multiple times if the config contains an EDL (External Dynamic List) that doesn't have an associated certificate profile.
PAN-292202 `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
`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 `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 `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 `This issue is now resolved. See` PAN-OS 11.2.8 Addressed Issues | (`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-288525

When the Enterprise DLP data filtering profile is configured with a Block action and is used in conjunction with Advanced Threat Prevention, which is configured with an action of reset-both, reset-server, reset-client, or drop for the HTTP Command and Control detector, Dropbox file uploads that exceed the maximum configured file size action will fail.
Workaround: Configure the Advanced Threat Prevention Inline Cloud analysis (ObjectsSecurity ProfilesAnti-Spyware) action for the HTTP Command and Control detector to alert.

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-286306 `This issue is now resolved. See` PAN-OS 11.2.8 Addressed Issues | When getting transceiver information from ESCC for SFP 25G modules, the transceiver code incorrectly displays Unknown instead of 25GBase-SR.

PAN-286231
`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-285061 | When Enterprise DLP is enabled, file uploads might unexpectedly fail when 100 continue response is received from the server during file uploads.
PAN-284700 | File downloads for content encoded with zstd (Zstandard), such as specific content from box.com, fail when using Enterprise DLP because zstd decompression is not supported in PAN-OS.
PAN-284067 `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-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 | (`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-279901
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-279415 `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-278688
`This issue is now resolved. See PAN-OS 11.2.11 Addressed Issues`

(`PA-7500, PA-5500, and PA-3500 firewalls only`) When DNS Security packet capture is enabled and a domain name has a length of 62 characters, the DNS Security threat log entry is not generated. On the affected platforms, this condition can also trigger a pan_task crash due to shared memory corruption.
Workaround: Disable DNS Security packet capture in anti-spyware profiles (ObjectsSecurity ProfilesAnti-Spyware) and in the DNS Policies tab, set Packet Capture to disable.

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.

PAN-254108

when upgrading or downgrading a Panorama management server (PanoramaSoftware), managed device (PanoramaDevice DeploymentSoftware), or standalone firewall (DeviceSoftware), 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.
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 (PanoramaHigh 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 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 (PanoramaManaged 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.
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

PAN-197588 | The PAN-OS ACC (Application Command Center) does not display a widget detailing statistics and data associated with vulnerability exploits that have been detected using inline cloud analysis.
PAN-197419 | (`PA-1400 Series firewalls only`) In NetworkInterfaceEthernet, 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 (CommitPush to DevicesEdit Selections or CommitCommit and PushEdit Selections).

PAN-195968

(`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 (PanoramaManaged DevicesSummary) 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 and select CommitPush 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.
