The earliest recollection of this bug is traced back to PAN-OS 10.1.0 - July 22, 2025. This bug is fixed in PAN-OS versions 9.1.17, 11.0.2, 10.2.5, 10.1.10. Fixed an issue on Panorama where virtual memory usage exceeded the set limit, which caused the configd process to restart. On M-600 appliances in an Active/Passive high availability (HA) configuration, the configd process restarts due to a memory leak on the Active Panorama HA peer. This causes the Panorama web interface and CLI to become unresponsive. Workaround: Manually reboot the Active Panorama HA peer.
