Please elaborate on what evidence leads you think this indicates a problem with the underlying server where the tests ran.

[Anita Kuno (anteaya)]

I submitted https://review.openstack.org/#/c/62930/ to turn on devstack exercises for master and havana for neutron in check and gate so that we can get more information on this bug.

Marking as resolved, it appears this was fixed back in March.
