Hi All,
We are trying to deploy Openstack in our production environment. For
networking we are using DVR with out L3 HA. We are able to create 114 VMs
with out any issue. After creating 114 VMs we are getting the below error.
Error: <html><body><h1>504 Gateway Time-out</h1> The server didn't respond
in time. </body></html>
Neutron services are getting freezed up due to a persistent lock on the
agents table. it seems one of the network node is holding the lock on the
table. After rebooting the network node, the Neutron CLI was responsive
again.
Neutron agent and neutron server is throwing below errors.
Neutron-server errors:
ERROR oslo_db.sqlalchemy.exc_filters "Can't reconnect until invalid "
ERROR oslo_db.sqlalchemy.exc_filters InvalidRequestError: Can't reconnect
until invalid transaction is rolled back

Neutron agents errors:

Could you please provide us your valuable inputs or suggestions for above
errors.
Thanks,
