The earliest recollection of this bug is traced back to PAN-OS 8.1.10 - July 22, 2025. This bug is fixed in PAN-OS versions 8.1.10. Fixed an issue where an incorrect SSH key initialization caused a process ( pan_comm ) to stop responding every 15 minutes when you configured an SSH proxy on the firewall.
