25.11: Fatal trap 12 on reboot

w0w

Both HA firewalls panic with a “fatal trap” during reboot—one on every boot, the other only occasionally.

Has anyone else seen something similar?

Hmm, what are those running on? They are both the same hardware?

Do you have the backtrace from the panics?

@stephenw10
Different hardware, one of them were running on the procmox 9 and looks like a bit different backtraces too. Yes I have a couple of backtraces from both firewalls. Currently running 25.07.1 and no traps observed. Can I upload it somewhere?
