CMAPI Cannot Communicate When Running As Non-Root

Our CMAPI service.template has the "root" user assigned. When changing that to another user like "mysql", CMAPI appears to start up correctly however communications between nodes does not work. Nothing but timeouts.

All folders involved are owned by mysql, all nodes in the cluster have the same config.
