Hi Volodymyr,
This is a known issue with the neutron (neutron-lbaas) database
getting out of sync and/or not properly handling driver errors.
This is one reason we are moving to deprecate neutron-lbaas. If you
can, we recommend you move to exclusively using Octavia without
neutron-lbaas.
The fundamental issue is that neutron-lbaas does not use database
transactions properly and does not lock records and the API correctly
so multiple requests/threads can modify neutron database records for
the load balancers. This is particularly an issue if you are doing a
high rate of changes against the neutron-lbaas API. To correct all of
these would require rewriting a significant amount of the
neutron-lbaas API code which doesn't make much sense given we are
moving towards deprecating it in favor of the Octavia API that does
not have this issue.
To mitigate this to some degree you can enable the multiple
synchronization features that push data back to the neutron database
correcting the inaccuracies in the neutron database.
event_streamer_driver and sync_provisioning_status can be enabled in
the octavia.conf [health_manager] section.
https://docs.openstack.org/octavia/latest/configuration/configref.html#health_manager.event_streamer_driver
This tells octavia to be aggressive at pushing status information back
up to the neutron database getting it back in sync with reality.
