，我使用wso2esb對它進行了配置以進行消息處理。使用Active MQ 5.10版本的活動MQ tcp連接失敗
大約7-10天后，活動MQ正在拋出tcp連接失敗異常，因爲ESB未收到成功的tcp連接，因此未能在隊列中提交消息。
在這種情況下，我重新啓動服務器，並再次運行7-10天，同樣的事情重複。
我的問題是
什麼可能是積極的MQ的確切原因停止給成功的TCP連接..？
爲什麼重啓服務器後它恢復正常狀態..？
有沒有最好的解決方案，以在來這個問題..
的內存配置，activemq.xml中文件

這裏是一個被放置在消息隊列中的代理服務。在代理服務，它會檢查用戶認證是否是真的，用戶可以在隊列中的位置信息，在這裏我使用的是類中介那裏，因爲它與主動MQ連接，並把消息

ActiveMQ中的消息數量日增？您如何使用AMQ，使用JMS代理服務和MessageStore？ –
嗨@ Jean-Michel感謝您的回覆，我正在使用ESB代理服務，它將在隊列中放置消息，並使用其他JMS代理服務來監聽此隊列並處理它。經常有消息進入隊列，無法處理任何問題，直到Active MQ成功連接到ESB。 – user4045063
我發佈了第一個答案，但告訴我在ActiveMQ中，如果發生故障（在隊列中等待數千條消息），消息的數量是否增加 –
