This bugzilla has been removed from the release and needs to be reviewed and Triaged for another Target Release.
I did not see similar failure in 10, if it is in 10, it is not as easy to reproduce it.
OSP10 is affected because we backported the patch there too. Indeed the error is not 100% reproducible, otherwise it would not even merge in upstream.
code verification on OSP10 $ rpm -qa |grep openstack-neutron-9 openstack-neutron-9.2.0-11.el7ost.noarch /usr/lib/python2.7/site-packages/neutron/plugins/ml2/plugin.py
