Currently running 6.7.2. Started seeing this issue after upgrading to 6.7.0 and then rolled back to 6.5.1. However, I still saw the issue occasionally on the older version. I'm not sure which docker is crashing - I run Plex, Radarr, Sonarr, and binhex-Sonarr and others . Every 1-3 days I see 100% CPU load and dockers not responding and I need to restart the array. I think it is probably Plex that crashes based on a Reddit thread I saw. From Reddit I understand that most people are able to role back to 6.6.x and not see the issue, so the fact that I still saw the issue after rolling back to 6.5
