I use Docker on Ubuntu 16.04 to have a container with Apache.

I have this error with docker status :
Couldn't run auplink before unmount /var/lib/docker/aufs/mnt/..... segmentation fault (core dumped).

EDIT1 : I stop this container and make a
docker run ... to have a new container from my image and I have the same result.
EDIT2 : When I go in
/var/lib/docker/aufs/mnt/, I have some directories. The only which has something (a core file) is directory in my error :
