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.

PAN-304756

This issue is now resolved. See PAN-OS 11.2.11 Addressed Issues

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

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

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

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-297295

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

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 thePanorama Config Audit page, some commit versions might display incorrect or missing data. Fields such as, COMMITTED BY, COMMIT DATE, andOBJECT 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-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

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

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

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-286306

This issue is now resolved. See PAN-OS 11.2.4-h10 Addressed Issues

When getting transceiver information from ESCC for SFP 25G modules, the transceiver code incorrectly displays Unknown instead of 25GBase-SR.

This issue affects PAN-OS 11.2.4-h6 This issue is now resolved. See PAN-OS 11.2.4-h7 Addressed Issues.

When a firewall receives an unexpected termination request for certain SSL sessions, NGFW dataplane might experience a slow buffer resource leak.

Workaround: Disable accumulation proxy on the NGFW.

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-285894

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

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-283467

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

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-282236

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

(PAN-OS 11.2.4-h1 through PAN-OS 11.2.4-h5)

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).
