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.

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.

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.

(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.

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.

(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.

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:

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.

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:

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.

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.

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.

(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.

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.

(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 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.

When applying filters or searching for logs in the PanoramaMonitorLogssection, you might experience slow performance.

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

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).

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.

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.

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.

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.

(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.

(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.

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

The command show auth radius-require-msg-authentic might return no output.

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 ( DeviceSetupServiceService Router Configuration).

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.

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.

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.

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

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.

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.

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.

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.

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:

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>

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.

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