Hello
When there is a DB node failure and the database briefly disconnects, the
following entry keeps appearing in the cloudstack-management.log until the
management service is restarted. All Cloudstack operations still function -
starting and stopping an instance for example
Cloudstack 4.9.3.1
Centos 7
3 CS management servers
3 active/active mariadb galera cluster - loadbalanced 1 active 2 standby
2018-05-02 09:27:40,685 ERROR [c.c.c.ClusterManagerImpl]
(Cluster-Heartbeat-1:ctx-64ee96a9) (logid:d15e998c) Unexpected exception in
