Description
Docker is working for a few weeks, then it is somehow not responding anymore. Some commands work, others not.
e.g. "docker stats" is hanging. "docker pa -a" works.
I searched through the various issues here that describe different hangs, but found nothing that solves my issue.
Restarting the docker daemon fixes the issue for a few days...
Steps to reproduce the issue:
- We just use docker and are starting / stopping containers.
Describe the results you received:
Docker hangs for whatever reason.
Describe the results you expected:
Docker should work as expected.
Additional information you deem important (e.g. issue happens only occasionally):
In other threads there was the hint of doing a SIGUSR1-Signal to dockerd and posting the result. Also, I have done an strace on the stuck "docker stats" command.
