Hello All, I would like to report that I have this issue also. Fortunately I have a 3rd party docker manager managing my containers (Komodo) so that they don't startup when the array starts up. After spending the day root causing the issue I find that the webGUI for Unraid becomes unresponsive if two docker containers are sharing an NVIDIA GPU via the docker nvidia toolkit. I anticipate this issue is manifesting across the board with people running HW acceleration for their plex/jellyfin containers and containers dedicated to transcoding or GPU compute tasks. I will continue to investigate. Only other things to note so far is that the unraid server is unreachable via webGUI but is REACHABLE with ssh and through my Komodo control console. stopping containers using the GPU does not bring back the webGUI.
