[akka-user] Akka 2.3.8: context.stop(self) and self ! PoisonPill fail on remotely deployed actors

[Brian Fowler]

Hi,

Can anyone help with the following in Akka 2.3.8

The actor

class SquarerActor extends Actor with ActorLogging {
  override def receive = {
    case SquareTask(id, number, _) => {
      log.info(s"${Thread.currentThread()} ${id}: ${number}^2 = 
${number*number} for ${sender}")
      context.stop(self)
    }
    case _ => {
      log.info(s"unknown message received")
    }
  }

}

when created locally from 

class TaskAllocatorActor extends Actor with ActorLogging {
  override def receive = {
    case task: SquareTask => {
      log.info(s"${Thread.currentThread()} received ${task} from ${sender}")

      context.actorOf(Props[SquarerActor],task.id) ! task
    }
    case _ => {
      println("Unknown Task")
    }
  }
}


works, but when deployed remotely using


class TaskAllocatorActor extends Actor with ActorLogging {
  override def receive = {
    case task: SquareTask => {
      log.info(s"${Thread.currentThread()} received ${task} from ${sender}")


      val actorRef = context.actorOf(Props[SquarerActor]
        .withDeploy(Deploy(scope = 
RemoteScope(AddressFromURIString("akka.tcp://Example2BoxTwo@127.0.0.1:2553")))),
 task.id)
      actorRef ! task
    }
    case _ => {
      println("Unknown Task")
    }
  }
}


the SquarerActor context.stop(self) fails, on the remote system the log is 
below, note that the remote actor receives the message and executes the receive 
block but the context.stop(self) fails

Using  self ! PoisonPill also fails in the same way


Thanks,


Brian
