I'm also on 6.12.3 with my HP Microserver G8 which is crashing since the update. Didn't have problems with 6.12.2. I disabled most of my docker containers despite Plex. So basically just Plex was running and a got a crash again. Now I also disabled Plex. So no VM or Docker container is running and I didn't have a crash until now. I want to wait until the parity check is finished. I already activated the syslog server and will activate Plex again after the parity check. If it than crashes again I will upload the syslog here.
