jstack results in "Windbg Error: WaitForEvent failed"

Question

On Windows 7, I try to get a stack trace from a Java process by executing the command

jstack.exe -F xxx

from another Java process, where xxx is the PID of the target process. I'm getting the error

Error attaching to process: Windbg Error: WaitForEvent failed!

Any idea why?

Because I left the company for which i asked my initial question, I somehow have to abandon it. – Slr

Answer 1

It might be that you need to run the command as administrator. If you do not have access rights to the process you will also get that same error message.

Answer 2

One of the possibilities (which may not be your case) is simply incorrect PID (see JDK-6313817 : SA: jstack -F on win32 needs more friendly handling of wrong PID)
