Shutdown does not work, supervisord hangs, valheim-server <defunct>, lots of cron processes

[fritzw]

Description

When trying to shut down the valheim server process cleanly in any one of the following ways, the supervisord process hangs:

• Sending SIGINT or SIGTERM to the valheim-server process
• Running supervisorctl shutdown in the container
• When cronjob tries to auto-restart at 5:00 o'clock

Symptoms

• The valheim_server.x86_64 process finishes as expected
• Two defunct valheim-server processes remain, which supervisord does not clean up (see attached file ps.txt)
• Any execution of supervisorctl hangs and does nothing
• supervisord spawns a lot of /usr/sbin/CRON -f processes, every 15 minutes (see attached file ps.txt)
• You can still docker exec -it $containername bash to run arbitrary commands in the container, except supervisorctl

Is there a work around for this? I'm guessing turn off auto-backups?
