2) hkumark pointed out

  I mentioned before it seems you are hitting the bug https://github.com/docker/docker/issues/10294

The conditions seems same as mentioned in the bug, so may be you would have to try

try upgrading kernel and see xfs issue has been fixed
Try ext4 filesystem rather than xfs which don’t have this problem
Try using a different machine to install contrail-test containers

Notes
-----
1) till R3.1 build 53, this issue was not seen; build 55, saw it once, from build 56 consistently seeing

2) Need a solution on making the centos docker for kilo to work

[Jeba Paulaiyan (jebap)]

This need to be handled by setting up separate test node in Sanity.

[Jeba Paulaiyan (jebap)]

This is not related to contrail code. This happened because we pull latest docker from upstream always and there was a bug in the upstream docker during this bug.
