P Suresh

Hi All,

Please let me know how can i get a stack Dump of the PID.

I tried the following and it is error-ing out.

\Oracle\Java\bin>jstack -F -l  5724 E:\Backup\LOGS\jstack.txt

Attaching to core E:\Backup\LOGS\jstack.txt from executable 5724, please wait...

Error attaching to core file: Windbg Error: OpenDumpFile failed!

Can a moderator please move this to the core Java community

@Suresh - is jstack running as the same user as the JVM you're trying to dump?  Are you running as Admin?  Do you have permission to write to that location?
