Amo*_*kar 6 java spring tomcat hibernate struts2
我有一个使用 tomcat 托管的应用程序，它在 12-18 小时后停止响应，我可以访问其他应用程序，如 tomcat 管理器，即 tomcat 进程正在运行，但我部署的应用程序停止响应。
我在日志中找不到任何可以直接得到某些原因的真正重要的东西。
我正在使用 struts2 + spring + hibernate + jasper + jquery。我的 tomcat 是 7.0.32 托管的 mysql 数据库。
请让我知道 - 如何知道究竟是什么原因，即调试出来，然后如何修复它。
如果需要，我可以添加一些日志，但不确定要添加哪些日志，哪些不是那么要求版主不要将此问题标记为错误或无法回答的问题，而是注释掉，我将根据需要添加/更新问题。
我已经阅读了一些相关的问题，但它们与我的真的不同。
提前致谢。
catilina.out 是在我停止服务器后创建的，并简要显示以下内容
