Akka Remote Controller / Workers getting disconnected and quarantined

Question

Remote Controller System:

Code:

private final ActorRef reaper = getContext().actorOf(Props.create(Reaper.class), "reaper");
private final ActorRef router = getContext().actorOf(Props.create(Worker.class).withRouter(new RemoteRouterConfig(new RoundRobinRouter(10), getNodes())), "router");

getnodes() is List<Address>

application.conf:

akka {
  log-dead-letters-during-shutdown = off
  actor {
    provider = "akka.remote.RemoteActorRefProvider"
    remote {
      enabled-transports = ["akka.remote.netty.tcp"]
      transport-failure-detector {
        acceptable-heartbeat-pause = 100s
      }
      watch-failure-detector {
        acceptable-heartbeat-pause = 100s
      }
      netty.tcp {
        hostname = "127.0.0.1"
        port = 2552
      }
    }
  }
}

Remote Worker System: Code:

 private ActorSystem system;

  public RemoteWorker(String name) {
    Config conf = ConfigFactory.load("remote");
    int port = conf.getInt("akka.remote.netty.tcp.port");
    system = ActorSystem.create(name, conf);
  }

  private void handleShutdown() {
    Runtime.getRuntime().addShutdownHook(new Thread() {
      @Override public void run() {
        System.out.println("Shutting down remote actor system...");
        system.shutdown();
      }
    });
  }

  public static void main(String[] args) {
    String systemName = (args.length == 0) ? "remote" : args[0];
    RemoteWorker remsys = new RemoteWorker(systemName);
    remsys.handleShutdown();
  }

remote.conf

akka {
  log-dead-letters-during-shutdown = off
  actor {
    provider = "akka.remote.RemoteActorRefProvider"
  }
  remote {
    enabled-transports = ["akka.remote.netty.tcp"]
    netty.tcp {
      hostname = ""
      port = 2553
    }
  }
}

Error: [WARN] [02/11/2014 14:50:26.728] [remote-akka.actor.default-dispatcher-17] [akka://..../system/remote-watcher] Detected unreachable: [akka.tcp://[email protected]:2553] [INFO] [02/11/2014 14:50:26.728] [remote-akka.actor.default-dispatcher-15] [Remoting] Address [akka.tcp://[email protected]:2553] is now quarantined, all messages to this address will be delivered to dead letters.

Your master expects the worker to listen at 127.0.0.1, but the worker listens at the computer’s default address.
