在我的应用程序中，以下内容作为客户端与JBoss 7.2.0系统上的JNDI/JMS接收器进行通信，以连接到JBoss 4.2.1系统上的接收器。它创建了一个发送队列和一个接收队列。我们使用这个配置已经连续运行了两个月，并且没有对任何一方进行更改。本地客户端应用程序安装了4.2.1 jbossall-client.jar和jnp-client.jars。
在正常活动后，我们开始收到org.jboss.mq.SpyJMSException: Exiting on IOE; - nested throwable: (java.io.EOFException) at org.jboss.mq.SpyJMSException.getAsJMSException(SpyJMSException.java:72)异常。
我们在没有更改任何内容的情况下重新启动了JBoss 7.2.0，当我们建立接收队列时，我们现在会收到org.jboss.mq.SpyJMSException: Cannot subscribe to this Destination: ; {...} Caused by: java.io.EOFException异常，该异常由我们的代码在 QueueReceiver receiver = session.createReceiver(queue);处抛出。我们还会在应用程序连续运行几天但多天无活动后开始抛出此相同异常。
我们重启了4.2.1系统以查看是否是问题，但什么也没有解决。事实上，我们可以通过让两个系统正常连接，然后重新启动4.2.1系统来复制此故障场景。这些错误开始在4.2.1系统关闭后抛出，并且7.2.0系统继续在4.2.1系统完全建立连接后无法重新建立连接（即使它应该能够这样做）。
在JBoss中停止然后启动应用程序无法解决此问题。 重新启动JBoss有20％的几率解决此问题（在上述强制故障情况下100％的机会）。 卸载应用程序，然后重新部署通常可以解决此问题。
可能导致这种情况的原因是什么？
这个war文件在我们的测试系统上运行良好，该系统与目标JBoss设置完全相同。使用相同代码从命令提示符中的测试应用程序与目标JBoss系统进行通信工作正常。
我怀疑问题出在JBoss 7.2.0本身上，或者这可能是超时问题吗？ 我如何检查或延长超时时间长度；这是可以从客户端端执行的吗？ 即使是超时，我在其余的start()重连之前就调用了stop()方法，但我仍然会收到异常；在那种情况下，它不会是超时问题，因为超时应该已重置。
