Hi,

We  have been  using akka clustering with two seed nodes  and we are seeing 
the behavior where both of  nodes are becoming leader and processing at the 
same time with just few milliseconds time difference.
If you stop one of them and then restart then things seem to be working 
normal. However after x number of days  it goes into this state again where 
in in both seeds act up as leaders. I have no clue as of now about this 
behavior.

Has any body encountered such issues with akka 2.2.x  version? Any help 
would be appreciated.


Thanks
Sowrabha


 We are using the below akka library

    "com.typesafe.akka" %% "akka-agent" % "2.2.0",
    "com.typesafe.akka" %% "akka-remote" % "2.2.0",
    "com.typesafe.akka" %% "akka-cluster" % "2.2.0",
    "com.typesafe.akka" %% "akka-contrib" % "2.2.0"


Below is a cluster configuration properties  on each of the seed hostnames

ClusterSystem.akka {
  actor {
    provider = "akka.cluster.ClusterActorRefProvider"
  }
  loglevel = "INFO"
  remote {
    log-remote-lifecycle-events = off
    netty.tcp {
          hostname = "hostname1"
      port = 2551
    }
  }

  cluster {
    seed-nodes = [
        "akka.tcp://ClusterSystem@hostname1:2551"
        "akka.tcp://ClusterSystem@hostname2:2551"
     ]

    auto-down = on
  }
}


ClusterSystem.akka {
  actor {
    provider = "akka.cluster.ClusterActorRefProvider"
  }
  loglevel = "INFO"
  remote {
    log-remote-lifecycle-events = off
    netty.tcp {
          hostname = "hostname2"
      port = 2551
    }
  }

  cluster {
    seed-nodes = [
        "akka.tcp://ClusterSystem@hostname1:2551"
        "akka.tcp://ClusterSystem@hostname2:2551"
     ]

    auto-down = on
  }
}
