java - JVM 消耗所有 CPU，大多数线程被阻塞。 JVM 错误？

coder 2024-03-03 原文

昨晚，一台服务器(JBoss 5.1GA, Java(TM) SE Runtime Environment (build 1.6.0_20-b02), Java HotSpot(TM) 64 位服务器 VM，在 VMWare 上的 Linux VM 中运行)突然开始使用 100% CPU。该应用程序是运行 Seam 的相当典型的 J2EE 业务应用程序，没有什么特别之处。当时负载极低。

我设法在进程被终止并重新启动之前获得线程转储(应用程序必须可用)。 JStack 在其死锁检测中出现异常；除此之外，大多数线程都处于阻塞状态。

这是 JVM 错误吗？我以前没见过。重新启动后一切正常，就像在该服务器上使用该应用程序后的几个月(定期更新)。

感谢您的任何建议。

稍作编辑的线程转储(以适应 SO 的帖子大​​小限制)如下。我删除了几个相同的线程(从 JBoss/Seam 中的各种线程池)，只留下堆栈跟踪中的最上面几行。

一种可能是您用完了堆空间。如果堆空间用完，JVM 将开始以惊人的速度消耗 CPU 进行疯狂的垃圾收集。
