Comment 5 for bug 1800417

Maybe using retry_db_errors decorator (https://github.com/openstack/neutron-lib/blob/0ff55899bad4082a965014ef753a3370bdeb2b43/neutron_lib/db/api.py#L157) for this method would help.
Can You maybe provide some additional neutron-server logs with errors which You got there? I don't think we spot such issue in rally job in our CI now.
Maybe You also have some rally scenario (or something else) which can help to reproduce this issue?
