Java高CPU线程| JBOSS EAP 6.3 |无法找到根本原因

问题描述 投票：0回答：1

非常感谢您的帮助和指导。

报告的问题是JBOSS的CPU使用率高（> 95％）。

  • 通过Windows服务器上的NSSM（https://nssm.cc）将[JBOSS EAP 6.3 alpha配置为服务
  • 我已经捕获了线程转储，并确定了高CPU使用率线程（总共5个），如下所示：nativeId（以10为底的十进制）：6428、2768、5904、6100和6840。这些线程消耗了大约15％每个CPU的数量。
  • 没有通过线程转储观察到死锁
  • 我还没有编写部署的代码，也没有这些线程的源代码，所以作为交付/实施团队的一部分，我有些困惑。

High CPU threads identified through psexplorer.exe

  • 对于这5个线程，堆栈跟踪的2种类型/变量如下：

    http- / 0.0.0.0：8080-187优先级：6-线程ID：0x0000000022d29800-nativeId：0x191c-nativeId（十进制）：6428-状态：RUNNABLE堆栈跟踪：java.lang.Thread.State：RUNNABLE在java.lang.Throwable.fillInStackTrace（本机方法）在java.lang.Throwable.fillInStackTrace（Throwable.java:783）

These threads are consuming around 15% of CPU each.它们可能会消耗较高的cpu，但不会被阻塞。
