Hi bob I comment on this bug, add my debug find. https://bugs.launchpad.net/starlingx/+bug/1917308 After host-swact, and quickly type in command "system application-apply stx-openstack", container tiller in pod armada-api will list installed release saved in postgres. But this list request will be failed with this log. 5432 is postgres listen port. 172.16.192.176 is armada-api pod cluster ip. 2021-03-01T11:38:56.600564874Z stderr F [storage/driver] 2021/03/01 11:38:56 list: failed to list: write tcp 172.16.192.176:35854->10.10.59.10:5432: write: broken pipe And after a while it will recovery, then "system application-apply", it will succeed. Any idea about this, maybe after host-swact, postgres is still launching and not ready for connection? You can reproduce this issue with latest daily build. BR!
