停止響應我有使用Tomcat應用程序託管，並停止12-18hrs響應後，我可以是工作訪問其他應用程序，如Tomcat管理器即tomcat的過程，但我部署的應用程序停止響應。Web應用程序後12-18小時
我無法找到任何在日誌中，我可以直接得到某些原因確實顯著。
我使用的Struts2 + Spring + Hibernate的碧玉+ +的jQuery。而我的tomcat是7.0.32託管的mysql數據庫。
請讓我知道 - 怎麼知道究竟是什麼原因即調試出來以後如何解決它。
如果需要，我可以添加一些日誌，但不知道要添加哪些日誌，哪些不需要請求版主不要將此問題標記爲虛假或無法回答的問題，而是註釋掉，我將根據需要添加/更新問題。
我看過一些相關的問題，但他們比我真的不一樣。
在此先感謝。服務器被我停止並顯示以下簡要

我現在看到我的應用程序沒有響應，在tomcat管理器中我看到 –
我也遇到了同樣的問題，我使用Hadoop，Hbase和Jquery。任何想法？ –
