Description of problem: OVN migration fails in case d/s CI job runs full neutron tempest suite before starting ovn migration. Note: usually d/s CI jobs execute a small subset of tempest tests before starting ovn migration and the issue does not happen. I tried to trigger a full tempest run before ovn migration and the issue reproduced. Tried 2 times and result was the same. from /var/log/containers/neutron/neutron-ovn-db-sync-util.log on controller-0 2023-01-26 18:09:27.099 100 ERROR ovsdbapp.backend.ovs_idl.transaction [req-19e57e7b-e7bb-4dbc-98ac-2b3655838395 -

Deploy ml2ovs HA environment, 3 controllers + 2 compute nodes. 2. Run full tempest run (networking tests from tempest repo + neutron upstream plugin + neutron downstream plugin test) 3. Start migration from OVS to OVN according to the official procedure https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/17.0/html/testing_migration_of_the_networking_service_to_the_ml2ovn_mechanism_driver/migrating-ml2ovs-to-ovn Actual results: Migration fails because of neutron-ovn-db-sync-util error. Expected results: No errors during neutron-ovn-db-sync-util execution. Migration completed successful. Additional info:
