    Issue ID
    Description
    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-296752
    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 driveā€™s SMART data. This condition leads to repeated reboots of the device, requiring a hard reset for recovery.
    PAN-295255
    Palo Alto Networks next-generation firewalls may experience service disruptions due to all_task process crashes when deployed in environments having non-uniform MTU and are terminating IPSec tunnels.
    PAN-294179
    This issue is now resolved. See 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
    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
    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-291288This 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.

    		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-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.

    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

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

    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).
