Clustering : Some time one of the rpc (2551) ports not coming up in 2 follower nodes of a 3 node cluster

I am running a 3 node cluster VMs on a Dell Host. I started the cluster after clean start-up, however one of the rpc (2551) ports not coming up in c1 and c3 node ( check below netstat command output for c1 and c3). From Jconsole I checked C2 is the leader.

I executed below features in ordered fashion. And enabled DEBUG logs in akka.conf for all the cluster nodes but put log:set INFO in karaf interface. I see only INFO messages in all log files.

All cluster nodes are reachable to one another.

opendaylight-user@root>feature:install odl-restconf-all
opendaylight-user@root>feature:install odl-mdsal-all
opendaylight-user@root>feature:install odl-openflowplugin-all
opendaylight-user@root>log:set INFO
