strange docker error when stop and starting a container

Question

I have been stopping and starting this container with no problem. Then suddenly I get this strange error.

see history of commands below

core@ip-10-32-251-200 /vol/jenkins/war/WEB-INF/lib $ docker ps

It is a issue detailed here. In the meanwhile you can workaround like this:

sudo systemctl stop docker-241d05c8d14f0b9f18d4f8647ac76a27097354aab5d92f1aaa6c9789a85e6e3d.scope

then start yout container
