Occasionally when files are being moved by Sonarr or Radarr to their destination on the NAS, the docker will become completely unresponsive. I can’t stop or kill it, and even rebooting takes a very long time. IOWAIT CPU% jumps up to between 30-50% according to Netdata, and just remains steady for as long as I leave it running. The only fix I’ve found is to reboot, stop, delete, and trash all data/config (I think it’s likely the move tries to resume as soon as s/radadd boot up).
I’ve seen several users with similar problems, but no solutions yet. I’ve tried:
Using older versions of each docker
Updating system / Docker-ce / docker-compose / docker-compose.yml version
Increasing mem, mem_swap, and shared container volume size for the affected dockers via docker-compose
Restoring older versions of each database
Nothing works, always the same result. I’m at my wits end, anyone have any idea?
