jstack 100％CPU

时间：2012-09-17 19:49:09

标签： java multithreading cpu jrun jstack

所以我试图弄清楚为什么我们的应用程序偶尔会消耗100％的CPU。我已经阅读了几个非常有用的stackovertflow帖子，但我认为在安全方面我想得到一些建议......指导......帮助......无论如何。真的，这也是我缺乏经验的堆栈痕迹。我真的很感激，如果有人可以在这里指出可能的罪魁祸首，并告诉我如此指示，以便我能更好地理解这一点。

值得注意的线程（在我看来）是等待监视器的：

我将推荐尝试使用JVisualVM - 它非常适合对线程进行排序。另一个好的选择是使用Eclipse，它也可以让您在调试模式下逐步执行各个线程。
