Hotfix versions were inferred because the vendor did not list them explicitly: 11.1.6-h1, 11.1.6-h2, 11.1.7-h1

The earliest recollection of this bug is traced back to PAN-OS 11.1.6-h3 - July 31, 2026. This bug is fixed in PAN-OS versions 11.1.6-h3, 11.1.7-h2. ( Firewalls in HA configurations only ) Fixed an issue where the all_task process stopped responding, which caused the passive firewall to repeatedly reboot.
