线程“WebContainer : 1545” 此线程可能已挂起

[谁是墨菲]

近日在进行压测后，发现应用服务器的CPU使用率一直为100%，通过观察服务器的CPU资源使用情况，发现没有一直占用很大资源的线程，后来通过观察Websphere的systemout文件发现有很多个线程处于挂起状态，但是具体什么造成的线程挂起却搞不明白，哪位熟悉的大神帮小白解答一下，代码如下：
[code=java][16-11-18 15:26:48:055 CST] 0000026a ThreadMonitor W WSVR0605W: 线程“WebContainer : 1545”（00000839）已保持活动状态 2737787 毫秒，此线程可能已挂起。在服务器中共有 1670 个线程可能处于挂起状态。
