Docker kill hangs, dockerd stuck, need to reboot my system to repair

OS is:
Linux amd64 4.4.0-128 Ubuntu 16.04 LTS

Docker package is:
Package: docker-ce
Architecture: amd64
Version: 18.05.0~ce~3-0~ubuntu

Trying to “docker kill” one of the running containers. Usually this succeeds, but sometimes this hangs forever. The docker kill command just doesn’t return.

This seems to happen more often when getting back to my workstation (which I don’t turn off normally) in the morning.

What I tried:

  • interrupt and rerun the same command. Does not work.
  • interrupt the command and restart the docker service. Does not work and it hangs.
  • kill the dockerd process, which immediately respawns. Nothing is resolved though, as things are exactly as before

Only a system reboot seems to solve this condition.

Would be great to know what/why this is happening and how to avoid or solve these problems.
Here’s some syslog messages from when I tried the above. If there’s any other info I can extract from my system, please let me know.

# This is yesterday. Everything working well so far...
