Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1597561 Title: L3 agent allows multiple gateway ports in fip namespace Status in neutron: Fix Released Bug description: At the end of deleting a GW port for a router, l3_dvr_db.py will look for any more router gw ports on the external network. If there are none, then it calls delete_floatingip_agent_gateway_port [1]. This should fan out to all l3 agents on all compute nodes [2]. Each agent should then delete the port [3]. In some cases, the fip namespace and the gateway port are not deleted. I don't know where things are going wrong. This seems pretty straight-forward. Do some agents miss the fanout? We know at least some of them are getting the fanout. So, it is definitely being sent. When I checked, the port had been deleted from the database. The fact that a new one is created supports this because if one existed in the DB already then it would be returned.
