Hello, I would like to propose a freeze exception for https://review.openstack.org/#/c/312253/ and https://review.openstack.org/#/c/312254/ . They address a bug in DVR that causes floating IPs to eventually break after an L3 agent has been restarted. It's a serious bug but it's very subtle because it takes a busy system and bad luck to trigger it.
If we decide against the back-port a workaround could be to advise all distros/operators to call the namespace cleanup script every time the l3 agent is restarted, which would prevent this issue, but at the cost of disrupting traffic on the agent restart. Cheers, Kevin Benton
