多线程性能问题，Linux下部署跑一会就停了，有日志

[BecksHwang]

项目跑了一个小时就停了，关闭tomcat有如下日志，有没有大神看看是哪里的问题，需要源码的问我。
日志如下：

先判断一下，是你的TOMCAT停了，还是只有你的几个线程停了 从日志里看不出来什么问题，可能本人水平有限 找问题的办法可以是 通过减少线程数、增加线程数，观察对系统造成的变化 屏蔽一些对资源（数据库连接、对象同步等）的代码，然后运行观察之

[BecksHwang]

感谢回复，是线程停了，因为同一个tomcat下跑着其他项目，其他项目还在正常运作。不太好观察，目前看的到现象就是项目跑了一个小时左右就停了。

[小灰狼]

再想办法检测一下，是线程真的停下来了，还是因为死锁了 我感觉死锁的可能性比较大。 如果有访问数据库，看看是不是连接池用尽了，这时可以再写个简单的 jsp 尝试得到数据库连接，如果不能获取，则表明你的连接被占用后没有释放，这要自己去查了 如果有对资源的同步，比如消费者、生产者队列等，就要仔细检查同步机制，定位到死锁的位置
