Description Ajay Kalambur 2017-02-24 17:00:49 UTC 
Started hitting the following bug which has been upstreamed but the fix is not present in RHEL/OSP10/neutron
https://review.openstack.org/#/c/361534/


Please backport this to OSP10/Newton as we started hitting this frequently. You can reproduce it with 3 controllers and a larger vlan range
