Having a weird issue lately where my Unraid server (7.1.4) is running, but the docker engine stops working with a message "Docker Service Failed to Start". The server didn't reboot or anything similar, but all the dockers stopped working and the only way to get them back is to power down the server and reboot; manually starting docker from withing settings doesn't start the service. The crash doesn't seem to have any pattern, but the service stops every few days usually no more than 10 days.

Attached are the diagnostic logs, but I can't tell anything is wrong from the logs. I already deleted and recreated the docker.img file and reinstalled all dockers, but the issue remains.

Any ideas?
