--- Comment #16 from Vivek Dasgupta <vdasgupt(a)redhat.com&gt; ---
Steps to reproduce ::

1) On RHEL 7 host, try to download rhel7 docker image

#docker pull registry.access.redhat.com/rhel

2)  Tag the image (NOTE this step may not be necessary to reproduce)

#docker tag registry.access.redhat.com/rhel rhel7

3) Run the image
# docker run -i -t rhel7 /bin/bash

4) Quickly exit out of the image

5) Try to run it again.
# docker run -i -t rhel7 /bin/bash

The issue can be reproduced easily if the container is re-run quickly after
exiting. Otherwise the issue occurs occasionally.
