Using wdb "set thread-check" options on HP-PA

Hello,

I have a multi-threaded applucation running on HP-PARISC (HP-UX B.11.23 U 9000/785)
The application is deadlocking, and initial investigation reveal a possibility of some threads exiting without releasing lock on mutex.

I saw that WDB provides for commands "set thread-check" to detect for threadlocks.

I used "set thread-check on thread-exit-own-mutex on"
however my application exits with

Trace library -- Non-recoverable error.
Out of memory.
Exiting...

I don't see the gdb process really increase in size. Any pointers on how to use this option?
Any WDB specific forum?

You need to look at the debuggee process. Saving this info in gdb would really slow things down.

It is lumped in with HP-UX devtools:

Hello Shweta,

Could you please try with the command: "set thread-check thread-exit-own-mutex on" (that is without the 'on' after 'thread-check') and let us know if it helps ?

Regards,
Jini.

Thank You Jini. This helped. Now the application is running in gdb. I hope to see some results.
