as you can see , there is a critical watchdog log that was causing the issue , however, the version is new 11.2.7-h8 and I would like to know if your recommendation is to move to the preferred release 11.2.10 any kind of suggestion would be highly cherished.

Hi @F.Pinar ,

A watchdog timer expiration is almost always a sign that a specific process became unresponsive for so long that the system's hardware monitor "pulled the plug" to force a recovery.

Seeing this on 11.2.7-h8 is particularly notable because that specific hotfix was released to address stability issues, yet you are still hitting a kernel-level hang.

Watchdog timer expired confirms the reboot was not a power failure or a manual restart. The system hung, and the internal timer reached zero.

Orphaned partition / inode clearing is a secondary effect. Because the system crashed suddenly, the file system didn't unmount cleanly. The "clearing orphaned inode" is just the firewall fixing itself during the subsequent boot.

I recommend moving to 11.2.10-h3 (the current "Preferred" release for the 11.2 train as of March 2026).

You can check the preferred releases on our Release Guidance Page:

https://live.paloaltonetworks.com/t5/customer-resources/pan-os-globalprotect-amp-user-id-preferred-release-guidance-from/ta-p/258304

I noticed in your logs that a TSF was already generated. I'd recommend opening a TAC case and specifically asking them to parse that file for MP-Monitor hangs. If the watchdog was triggered by a heartbeat failure, they can identify exactly which process (like mgmtsrvr, devsrvr, or all_pkt_proc) caused the freeze, which will confirm if the jump to 11.2.10 is the definitive fix for your specific crash.

Hope this helps !

in this case , TAC determined to proceed with a RMA to solve the issue. Morever, I was asking for Daemon that helped them to determine the RMA process.
