Recently I got a server with Ubuntu 18 and docker-ce 19.03.1. For some reason, my containers are constantly set to “paused” state and eventually docker becomes unresponsive after ~16-24hours. When I execute docker-compose unpause, the containers are unpaused but eventually get paused again. I cannot find a reason why docker would pause the containers online,
How can I diagnose this? How can I figure out why this endpoint to pause containers is being called? I enabled debug in daemon.json and I’m able to see that something is making the request to docker to pause the container. I have also tried changing to different compose/docker-ce versions available for Ubuntu 18 and they all exhibit this issue.
