March 19, 20188 yr I am experiencing an issue where the docker service is hanging/crashing and not restarting. My Plex container appears to be part of the issue as its the only one that appears to go down while this is happening.

March 19, 20188 yr Hi, I had the same issue. It happened after 6.5.0 upgrade. https://lime-technology.com/forums/topic/70083-rc6-call-traces/
March 20, 20188 yr Author interesting, I'll roll back to 6.4.0 then. I would have preferred to stay on 6.5.0 as the Ryzen fixes were enticing, but if this is going to continue I'll stick with 6.4.0 Edited March 20, 20188 yr by dkuhn

See here: Quote Too many issues with docker 17.12.x release, and we haven't had enough internal testing with 18.03.x release, so we are reverting back to 17.09.1. We are anticipating moving to 18.03.x in unRAID OS 6.6.
