podman --version
podman version 1.6.4

no dbsync containers run (or have run in a while)

[root@controller-0 heat-admin]# podman ps |grep sync fd7f9e4c5a94 under-ussuri02.ctlplane.example.com:8787/tripleou/centos-binary-swift-object:current-tripleo kolla_start 6 months ago Up 29 hours ago swift_rsync

VIP is pingable from the controller,pcs reports no issues and the overcloud is working fine.
I will do a more thorough networking check tomorrow as per your instructions.
Is there any other log that might be of interest?

The only thing that I might be seeing is in /var/log/containers/mysql/mysqld
https://paste.centos.org/view/1fe4cdf9

are these warnings about connection drops that might be relevant??
Any other points would be helpful
