PAN-307795

On a standalone Panorama, the system incorrectly generates system logs indicating a lost connection to its peer even when High Availability is not configured. You can safely ignore these logs, as they do not affect operations.

PAN-306502

TLS sessions using version 1.2 or earlier may fail when session traffic matches a decryption policy rule with the no-decrypt action under either of the following conditions:

If both of these conditions are met, the session is guaranteed to fail.

If both of these conditions are met, the session is guaranteed to fail.

If both of these conditions are met, the session is guaranteed to fail.

Both HTTP header insertion (ObjectsSecurity ProfilesURL FilteringHTTP Header Insertion) and SSL/TLS handshake inspection (DeviceSetupSessionDecryption SettingsSSL Decryption Settings) are enabled.

Both HTTP header insertion (ObjectsSecurity ProfilesURL FilteringHTTP Header Insertion) and SSL/TLS handshake inspection (DeviceSetupSessionDecryption SettingsSSL Decryption Settings) are enabled.

Log Successful SSL Handshake is not enabled in the decryption policy rule and neither Block sessions with expired certificates nor Block sessions with untrusted issuers is enabled in the attached decryption profile.

Log Successful SSL Handshake is not enabled in the decryption policy rule and neither Block sessions with expired certificates nor Block sessions with untrusted issuers is enabled in the attached decryption profile.

Workaround: Perform one of the following tasks:

Enable Log Successful SSL Handshake in all no-decrypt decryption policy rules.

Enable Log Successful SSL Handshake in all no-decrypt decryption policy rules.

Enable either Block sessions with expired certificates or Block sessions with untrusted issuers in the decryption profiles attached to the no-decrypt decryption policy rules.

PAN-305301

The timing of GlobalProtect lifetime expiry or inactivity logout notifications used for GlobalProtect SSL tunnels may cause the pan_task process to stop responding and the dataplane to restart.

Workaround: Select Network > GlobalProtect > Gateways > > Agent > > Connection Settings and change the value of both Notify Before Lifetime Expires (min) and Notify Before Inactivity Logout (min) to 0.

PAN-304756

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 might result in incomplete or inconsistent configurations across virtual systems.

PAN-304576

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-298505

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-294436

PA-410, PA-440, PA-450, and PA-460 firewalls

After upgrading to 11.1.6-h6, the Eth1/2, Eth1/3, Eth1/8, and HA interfaces (if configured) fail to display counters and statistics in the CLI and SNMP.

PAN-293673

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-292202

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-291288

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-290996

When performing an SNMP walk, the Connections Per Second (CPS) counters incorrectly return a value of 0 for each virtual system (VSYS), despite the firewall actively processing connections.

PAN-290235

The dscd process crashes continuously on MIPS platforms (for example, PA-850 firewalls) due to a runtime error related to an invalid memory address or nil pointer dereference. This occurs when the golang library upgrade in CIE is not compatible with the MIPS platform.

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-288097

Routed process may stop responding after changing MTU or any link parameters when OSPF and PIM are enabled on the same interface.

PAN-287056

A BGP export policy rule that matches on a next hop fails to block the advertisement of static routes, and the firewall incorrectly matches the egress interface IP address instead of the original next-hop IP address of the static route, which causes the deny rule to fail.

PAN-286897

The pan_task process might fail when the firewall attempts to forward files to the WildFire public cloud, which can cause the dataplane to experience heartbeat failures.

Workaround: Disable the firewall WildFire Analysis profile.

PAN-286848

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-286496

NGFW Clusters

URL-continue and override continue selections will function like a general URL-block action.

PAN-286306

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

PAN-286255

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

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.

When you run Commit and Push operations as a single action.

When you run Commit and Push operations as a single action.

When you trigger multiple parallel commit-all jobs at the same time.

When you trigger multiple parallel commit-all jobs at the same time.

Device groups and templates have different configuration synchronization versions.

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

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-285590

VM-Series firewalls deployed behind an AWS GWLB might experience 100% dataplane CPU utilization when an Anti-Spyware profile is applied to traffic.

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-282854

The Elasticsearch cluster fails to start after deploying dedicated log collectors in a multi-collector environment.

PAN-282236

The firewall doesn't reassemble IPv6 packets correctly after they are fragmented. IPv6 SSL sessions may not be established if the client hello arrives in multiple segments.

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-280532

When you use a single syslog server over TCP for log forwarding, and the connectivity to the syslog server breaks, syslog forwarding does not resume even after the connectivity to the server restores.

Workaround: Performing one of the following tasks:

Reboot the firewall.

Temporarily, configure syslog to use UDP, commit the configuration, revert to TCP, and then commit.

PAN-280471

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

PAN-279901

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

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 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

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

A decryption policy rule excludes this traffic from decryption and a Security policy rule (URL filtering) denies this session

To enable this fix, run the CLI command bug dataplane set ssl-decrypt accumulate-client-hello disjoined yes

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

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-279604

The scheduled SaaS application usage reports are incorrectly generated and only the login page appears instead of the intended report content.

PAN-279415

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-278322

VM-Series firewalls deployed behind an AWS GWLB might display an incorrect or empty Source User field in traffic logs and session details.

PAN-278296

The system MAC address of the aggregate interface is the same on both the active and the passive devices, causing some packets to be sent incorrectly to the passive device. This is causing the AE interface on the active firewall to not come up.

PAN-277417

Memory leak issues can occur during the parsing of server certificates used for SSL Inbound Inspection, preventing the firewall from completing inspection.

PAN-277090

When you enable Advanced Routing and configure a BGP Authentication profile, if you configure a Secret that includes any special characters apart from these seven special characters !@#%^_-, an error message displays, indicating that The value in this field is invalid.

Workaround: Don't include any special character apart from the !@#%^_- characters in the Secret for a BGP Authentication profile.

PAN-277034

WildFire reports might not fully display or be downloadable because some static resources fail to load.

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-275905

A high volume of incoming logs to a Collector Group can significantly increase CPU usage on the Elasticsearch and Management Server, potentially causing process instability or crashes.

PAN-275601

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

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-274146

VM-Series firewalls deployed behind an AWS GWLB might crash and reboot unexpectedly if tunnel sessions are moving through the firewall.

PAN-272085

When DoH is enabled for DNS Security, multiple DoH transactions in a single HTTP/1 connection might unexpectedly cause the firewall to crash and reboot.

Workaround: Manually disable DoH support for DNS Security using the set deviceconfig setting dns-over-https enable no CLI command. Alternatively, you can remove the DNS Security configuration used to handle DoH traffic.

PAN-269193

When multiple application are configured for GlobalProtect Clientless VPN, users are directed to the first application instead of portal page with a list of application.

PAN-262556

The ElasticSearch cluster health status might continue to remain yellow for an extended period after upgrading to PAN-OS 11.1

PAN-261429

When an NGFW cluster agent crashes and doesn't recover, leader election will take approximately 45 seconds to begin and traffic failover will occur during that time.

PAN-250903

PA-7500 Series firewalls only

In a congestion scenario on an HSCI port of an NGFW cluster node, the QoS priorities of cross node traffic streams might be reversed if you're using the default QoS profile with class1 to class8 set as high to low.

PAN-247974

PA-7500 Series firewalls only

LACP flap is expected during a device failover in an NGFW cluster due to an L2 ctrld restart on the new leader node.

PAN-240529

PA-7500 Series firewalls only

Cloud application information is missing from traffic logs on NGFW cluster nodes.

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

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 serialno <satellite_serial>

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

PAN-234015

PAN-224502

The autocommit time of the VM-Series firewall running PAN-OS 11.1.0 might take longer than expected.

PAN-220180

Configured botnet reports (MonitorBotnet) are not generated.

PAN-207733

When a DHCPv6 client is configured on HA Active/Passive firewalls, if the DHCPv6 server goes down, after the lease time expires, the DHCPv6 client should enter SOLICIT state on both the Active and Passive firewalls. Instead, the client is stuck in BOUND state with an IPv6 address having lease time 0 on the Passive firewall.

PAN-207611

When a DHCPv6 client is configured on HA Active/Passive firewalls, the Passive firewall sometimes crashes.

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.

Log in to the Panorama web interface of the active-primary HA peer.

Log in to the Panorama web interface of the active-primary HA peer.

PAN-207040

If you disable Advanced Routing, remove logical routers, and downgrade from PAN-OS 11.0.0 to a PAN-OS 10.2.x or 10.1.x release, subsequent commits fail and SD-WAN devices on Panorama have no Virtual Router name.

PAN-206913

When a DHCPv6 client is configured on HA Active/Passive firewalls, releasing the IPv6 address from the client (using Release in the UI or using the request dhcp client ipv6 release all CLI command) releases the IPv6 address from the Active firewall, but not the Passive firewall.

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.

Log in to the Dedicated Log Collector CLI.

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-194978

PA-1400 Series firewalls only

In NetworkInterfaceEthernet, hovering the mouse over a power over Ethernet (PoE) Link State icon does not display link speed and link duplex details.

PAN-187685

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.

PAN-164885

On the Panorama management server, pushes to managed firewalls (CommitPush to Devices or Commit and Push) may fail when an EDL (ObjectsExternal Dynamic Lists) is configured to Check for updates every 5 minutes due to the commit and EDL fetch processes overlapping. This is more likely to occur when multiple EDLs are configured to check for updates every 5 minutes.
