活动MQ tcp连接失败

我使用的是活动MQ 5.10版本，我已将其配置为wso2esb以进行消息处理

大约7-10天后，活动MQ将抛出tcp连接失败异常，因为ESB未接收到成功的tcp连接，所以无法在队列中提交消息

在这种情况下，我重新启动服务器，它将再次运行7-10天，同样的事情会重复

我的问题是

活动MQ停止提供成功tcp连接的确切原因可能是什么

为什么重新启动服务器后会恢复正常状态

有没有解决这个问题的最好办法

activemq.xml文件中的内存配置

您应该共享proxys配置，但始终可以验证：

• 您已设置cachelevel以避免每次扫描时出现新连接：

  消费者

• 您已要求每次扫描时使用所有消息：

  -1

ActiveMQ中的消息数量是否与日俱增？您如何将AMQ与JMS代理服务、MessageStore结合使用？您好@Jean Michel谢谢您的回复，我使用ESB代理服务将消息放入队列，其他JMS代理服务将侦听此队列并对其进行处理。消息经常会到达queu在Active MQ成功提供到ESB的tcp连接之前，我会发布第一个答案，但告诉我当if开始失败时，ActiveMQ中的消息数量是否在增加（队列中等待数千条消息）发生此问题时，队列中没有等待的消息。收到所有消息后，将立即处理这些消息。
