Tomcat High Cpu Usage
提问by Rockroxx
We have 2 tomcat instances running on the same server of which one is causing regular high cpu load. I have run a profiler on the server but it has only told me that java.lang.Thread.run() is hogging the cpu nothing more conclusive. The cpu spikes are from 0% to 45/55% every 4 seconds.
我们在同一台服务器上运行 2 个 tomcat 实例，其中一个导致常规的高 CPU 负载。我在服务器上运行了一个分析器，但它只告诉我 java.lang.Thread.run() 正在占用 CPU，没有什么更确定的。cpu 峰值每 4 秒从 0% 到 45/55%。
Is it possible that it is not the application itself but a misconfiguration of the apache part? How would i go about finding the issue?
是否有可能不是应用程序本身而是 apache 部分的错误配置？我将如何去寻找问题？

Maybe blocked threads ? Look here for how to make thread dumps and check for blocked threads.
也许阻塞的线程？在此处查看如何进行线程转储并检查阻塞的线程。
