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?

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.
