[Freeswitch-users] Crash in mod_opal when hanging up call...

[Peter Olsson]

Hello everyone. I've been following this project for quite some time now, but I never got the time to test it. But today I finally had a day off from work, so I could sit and play around with it for some time :) Everything wen't really smooth - even though I built everything from scratch on a Windows machine, including mod_opal (linked against the opal library). And with the docs I found I didn't even have to search Google to get it up and running :) So first of all - what a great job, guys - I'm really impressed, and the code seems really stable as well!

My setup right now is FreeSWITCH in Windows XP, with both SIP and H323 enabled. And most of the stuff works just fine. However, I think I've found a bug in mod_opal - it sometimes causes FreeSWITCH to crash when hanging up a call. I think that mod_opal is considered to be in beta stage still, so I'm not all that surprised. :) Check the error found in the log below. Does anyone have any ideas? It's pretty easy to reproduce, just dial in to FreeSWITCH using H323 and hang up the call, for me it happens maybe 2 out of 5 times.

I'm using latest SVN trunk versions (checked out today), for both FreeSWITCH and for opal/ptlib.

If you need further information, or if I should file a jira case, please get back to me, and I'll try to help out as much as possible.
