ActiveMQ 5.11.1不断抛出EOFException并且不会发送消息

Question

我有一个在几个不同的服务器上运行的AMQ 5.11.1实例。它们都配置相同，并连接到同一网关。在一个特定的服务器上，我不断看到此消息：

调试输出无济于事，并且我无法确定导致该连接不断断开的服务器实例之间的区别是什么。

它具有足够的内存：

jps -v | grep activemq
40359 activemq.jar -Xmx8G

这是我的activemq.xml的一部分：

   <networkConnector name="linkToGateway"
       uri="static:(tcp://gateway:55616)"
       networkTTL="3"
       duplex="false"
       prefetchSize="2"
   >
        <excludedDestinations>
            <queue physicalName=">"/>
        </excludedDestinations>
        <staticallyIncludedDestinations>
            <queue physicalName="server-01.lookupdata" />
        </staticallyIncludedDestinations>
    </networkConnector>

任何帮助，将不胜感激！

我遇到了同样的问题，并通过配置OpenWire协议解决了它。默认的OpenWire设置期望连接在10秒内发生流量，此后30秒内。您将在日志中看到实际使用的值。我通过设置以下方式禁用了此超时（在我的方案中可以）...wireFormat.maxInactivityDuration=0

整个网址：

tcp://localhost:61616?connectionTimeout=0&keepAlive=true&useInactivityMonitor=false&wireFormat.maxInactivityDuration=0

或确保立即并定期使用连接。

本来我打算将蒂姆·比什的答案标记为正确，但他似乎删除了它。

网络连接是问题所在。某些连接被切断，在调查和解决这些问题后，事情开始顺利进行。
