Please let me know whats the issue

I'm assuming you are using the docker "quick start" instructions? This looks like a problem caused by a stale docker image. I clean up my docker images and containers every now and then by running the following (you may need to adapt it, depending on your installation):

docker rm -v $(docker ps -a -q -f status=exited)

docker run -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/docker:/var/lib/docker --rm martin/docker-cleanup-volumes
