I've been having issues where docker will randomly stop working. I have the auto update plugin and I've woken up to none of my docker containers appearing in the docker tab. I've had to reboot to get it to appear once again. I've also had it where the server is on but nothing works and not even the unraid GUI is accessible. I started monitoring logs and this is the last thing that was logged before it crashed.

I'm not sure if this is related but I also did find these errors in the log
