我必须运行jmap才能获取我的进程的堆转储.但jvm回来了:

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

所以我使用了-F:

./jmap -F -dump:format=b,file=heap.bin 10330
Attaching to process ID 10331, please wait...
Debugger attached successfully.
Server compiler detected.
JVM version is 24.51-b03
Dumping heap to heap.bin ...

1. 使用-F 是可以进行堆转储吗？
2. 我等了20分钟还没完呢.有什么想法吗？
