Floating IP agent gateway IP addresses not released when deleting dead DVR L3 agents

Solution In Progress - Updated -


  • We had a report that all IPs were being used in a network where there should only have been a handful of IPs in use.

  • Looking into it we found that many ports were allocated and marked ACTIVE by neutron. These ports were of device_owner: network:floatingip_agent_gateway.

  • We were pointed to a launchpad bug which seems the most likely cause for our issue.
