我最近有一个问题，即使是一个简单的akka微内核模型的应用程序。它不能停留在亚马逊ec2。这里是日志

Starting Akka...
Running Akka 2.0.5
Deploying file:/data/akka-scala/akka-2.0.5/deploy/catchif2_2.9.2-0.1-SNAPSHOT.jar
[DEBUG] [03/02/2013 09:35:32.626] [main] [EventStream] StandardOutLogger started

Starting up com.catchif.HelloKernel
Successfully started Akka

Shutting down Akka...
Shutting down com.catchif.HelloKernel
Received message 'HELLO world!'
Successfully shut down Akka

基本上它会立即自动启动和关闭。
我在我的Mac电脑上运行同样的代码。它保持完美。日志中除了这个之外没有额外的信息：

03/02 09:35:33 INFO [hellokernel-akka.actor.default-dispatcher-4] a.e.s.Slf4jEventHandler - Slf4jEventHandler started
03/02 09:35:33 DEBUG[hellokernel-akka.actor.default-dispatcher-3] a.e.EventStream - logger log1-Slf4jEventHandler started
03/02 09:35:33 DEBUG[hellokernel-akka.actor.default-dispatcher-3] a.e.EventStream - Default Loggers started

代码也非常简单。

import akka.actor.{ Actor, ActorSystem, Props }
import akka.kernel.Bootable

case object Start

class HelloActor extends Actor {
  val worldActor = context.actorOf(Props[WorldActor])

  def receive = {
    case Start ⇒ worldActor ! "Hello"
    case message: String ⇒
      println("Received message '%s'" format message)
  }
}

class WorldActor extends Actor {
  def receive = {
    case message: String ⇒ sender ! (message.toUpperCase + " world!")
  }
}

class HelloKernel extends Bootable {
  val system = ActorSystem("hellokernel")

  def startup = {
    system.actorOf(Props[HelloActor]) ! Start
  }

  def shutdown = {
    system.shutdown()
  }
}

不知道为什么会这样。我确实看到它在亚马逊上停留了一次，但后来一直失败。
