** Description changed:

  For a Yoga base deployment (OVN: 22.03, OVS: 2.17.2) the neutron-ovn-
  metadata-agent continually reconnects to the ovn-central services via
  ovn-relay - the inactivity probe timeout is set to 60 seconds in OVN
  central and on the client side so I think the issue is that the ovn-
- relay is probing with a 5 second timeout and then resetting connections:

  by passing the ovn-relay and communicating directly with the SB db
  server worked around this issue.
