asterisk users - Mar 2006 - RE: MeetMe freezes machine with Junghanns

Dollars to donuts it is related to these two posts, but no one seems to know
where or why it happens - this issue doesn't seem to be related to one
specific piece of hardware:

Post 1)

*********************************************************
Anyone ever seen MeetMe cause * to crash? Specifically, it happens
consistantly if someone begins to enter a conference and then decides to
hangup while Allison is introducing them - like playing back
"conf-onlyperson". This has been seen with the MeetMe participant
connecting
via IAX and SIP (not saying it doesn't happen with Zap, just that I
haven't
seen it).

The box is * 1.2.5, Zaptel 1.2.4, a TDM400P loaded with 3xFXO cards,
Mandriva 2006 Free.

Symptoms of the crash: once the participant hangs up, the CLI seems to
freeze. One more call instance can be initiated, and the system will seize
within seconds (for instance, an audio prompt will deteriorate and then stop
dead). This behavior reminds me of the memory leak issue and time bomb bug,
perhaps they do the same damage as this.

Solution right now is to disable MeetMe, which isn't a solution as much as
an amputation. Anyways, here is the CLI output, note the WARNING:

Thank you for the hint. Now finaly I can 100% reproduce the problem. Yes, if
I hang up during Playing 'conf-onlyperson' my machine freezes. It's
not a
GSM Enconding problem as I suspected first, this happens with every
encoding.

Freeze!

Any other who can reproduce that freeze?

Kernel 2.6.15 / * 1.2.5 / ztdummy 1.2.4

 There's been two very recent commits (one less than an hour ago) that
may very well correct your issues.
