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
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
Traffic that is incorrectly identified as unknown-tcp/unknown-udp eventually drops due to an App-ID resource limitation issue.
PAN-301801
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
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_v5D4_v2/DS4_v2 to D8ds_v5D5_v2/DS5_v2 to D16ds_v5 Azure VMs with ephemeral storage can only be resized to another type with ephemeral storage.
D3_v2/DS3_v2 to D8ds_v5
D4_v2/DS4_v2 to D8ds_v5
D5_v2/DS5_v2 to D16ds_v5

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 drive’s SMART data. This condition leads to repeated reboots of the device, requiring a hard reset for recovery.
PAN-295803
A configd memory leak occurs post commit (during Panorama connectivity check), potentially leading to OOM (out of memory condition) and device reboot.
PAN-294179
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-292344
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
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-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.

PAN-284067
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
