Hi All,
It's been a while I'm experiencing os crashes with unraid.
The most Common one is the "Kernel Panic - not syncing: Fatal exception in interrupt". This is tricky since even I have syslog enabled (to remote host + copy to flash) I was not able to see any real logs that would reveal the smoking gun.
Like this below... after a successful backup the next message is after I did a hard reset on my machine. syslog-127.0.0.1-kernelpanic.zip

Dec 6 13:28:25 Pandora-NAS root: Delaying execution of fix common problems scan for 10 minutes
The diagnostics package pandora-nas-diagnostics-20211206-1331.zip that created post this recent crash is attached as well.
I believe that the issue started after I added a quad NIC into my system. Although I was running with it for few months without any issues.
Till once the OS crashed. Since then it had countless crashes with a various duration of 1-14 days.
My docker settings:
I have many docker container although the 3 that runs most of the time with br0 are : qbitorrent, plex, tautulli. The rest are either in bridge mode or not running.
I read many articles and I saw that it could be something with VLANs although I'm not sure how to adjust my settings.... also it seems that others experiencing the same even on 6.10.0-rc2.
Although the remote symptoms (Web UI, shares, ssh are all unavailable) are the same, I had 2 cases when the console didn't showed the kernel panic message, but the command prompt was "working".
I got invalid password although I provided the correct one hence the authentication engine should failed.
I was managed to login, ip settings were good and I was able to ping my gateway although the OS was not accessible. diagnostics was failed, but the syslog syslog-127.0.0.1-notaccesible-20nov.zipshowed some kernel info ~ midnight, then the next log is indicating the time I did a hard reset.

Any help would be much appreciated since I hit my array with parity checks (7+ hours) each time I have a crash, and I had many...
