docker unable to start after shutdown

[thezoggy]

I run this docker on unraid 6.8.3 (havent touched it in awhile).

At times if I stop the docker it doesnt shutdown cleanly and on tosses up the error about X server lock still existing. Then with --restart="on-failure" set on the docker it will get stuck in restart loop.

# cat X.log

I can edit the docker then start to 'fix' for that instance and it works fine. Which I'm guessing is pruning out the tmp lock..

Testing this in controlled manner to replicate, docker is running.. now stopping via cli:

root@husky:/mnt/cache/appdata/.kodi# docker container ls

Starting docker via unraid via unraid gui it shows 'started'. However looking at the cli I see its actually just in a restart loop:

and logs just show:

and trying to connect to docker fails

root@husky:/mnt/cache/appdata/.kodi# docker exec dd149d354daf ps -A
Error response from daemon: Container dd149d354daf124a869a2ccbd63fb6b8651b0f01cd1ab3c38f0ac5a94523223e is restarting, wait until the container is running

Have tou try to docker rm and they restart it ?

I mean start a new containers from the same image

[thezoggy]

it looks like when you 'edit' the docker in unraid it does just that.. remove old one to rebuild. which is why it works. but stopping the container then starting it doesnt work because it doesnt stop cleanly
