无法对我的java应用程序运行jstack -l
无法对我的java应用程序运行jstack -l
提问于 2014-09-22 17:41:11
我的应用程序卡住了，然后我想检查线程状态。但是我不能通过jstack -l 33822从我的应用程序中获取线程转储。
Unable to open socket file: target process not responding or HotSpot VM not loaded
The -F option can be used when the target process is not responding然后，我使用-F尝试进行线程转储。我得到一个错误，如下：
Attaching to process ID 33822, please wait...
Debugger attached successfully.
Server compiler detected.

Can't print deadlocks:10它是JVM的defect吗？

你确定线程转储不会发生吗？我们得到这个错误，但在一小段等待之后，我们仍然得到一个线程转储
