      OwnerSupervisor - Cluster Singleton Manager Actor which is responsible for assigning the owners to the DOMEntities is getting terminated in the following scenarios,

       

      1. When trying to do multiple Netconf device mounts or multiple Deletes of netconf devices in an ODL cluster setup
      2. When the ODL instances with the master mounts gets restarted and joins the Cluster.

       

      And it never gets restarted again and due to which further new mounts are failing as their is no actor to assign owners entities.

      As per the akka docs and cluster singleton manager actor, ideally it should be always running in any one of the ODL instances in the cluster
