Docker daemon not response

I am newby in docker-engine. I install
docker --version
Docker version 1.9.1, build 08eb66d
on Oracle Linux
uname -a
Linux istestci1.sigma-it.local 4.1.12-32.2.1.el7uek.x86_64 #2 SMP Sun Jan 31 23:50:34 PST 2016 x86_64 x86_64 x86_64 GNU/Linux
Configure certificate and using docker-engine via io.fabric8:docker-maven-plugin for integration tests.
Bun after week of using docker-engine it is broke down. I can not ever see the list of container:
docker ps -a
this command stuck without any message to console or /var/log/message.
systemctl status docker -l
say that: …active (running)…
and surprise:
: level=warning msg=“failed to cleanup ipc mounts:\nfailed to umount /var/lib/docker/containers/0b68738e40a81072fcffee2603f9cc01fd1bcb88bacef1a8ed90a5b373340266/shm: invalid argument\nfailed to umount /var/lib/docker/containers/0b68738e40a81072fcffee2603f9cc01fd1bcb88bacef1a8ed90a5b373340266/mqueue: invalid argument”

How fight with that?

PS. Restarting the daemon over and over kept giving the failure.

Problem has gone after reinstall docker and clear /var/lib/docker folder.
But root of the problem in my .bashrc I fogot add


when configure certificates
