Hi Sowrabha, it looks like you are getting network partitions which together with "auto-down=on" result in two clusters to be formed. You can find more information about this situation here <http://doc.akka.io/docs/akka/2.2.0/scala/cluster-usage.html#Automatic_vs__Manual_Downing> .
You might want to turn auto-down off and manually or automatically react to unreachable nodes by restarting some part of the cluster when network has healed.
