[asterisk-users] asterisk crash and core dump: format_mp3.so

[Vieri]

Hi,

My Asterisk server process irregularly segfaults, ie.
it usually works fine (is stable) when there's low
traffic but repeatedly crashes during morning hours
when there are more calls.

I gdb'ed the core dump files and found that the
culprit may be format_mp3. So I disabled MOH today and
will see if that's the cause.
I know that mp3 files are known to cause * crashes but
what I don't understand is why it doesn't *always*
crash (ie. why doesn't it crash even when there's low
traffic? I mean, if the offending code is in the mp3
format then it should *always* crash, right?).

I'm pasting the bt below to see if someone has any
suggestions on this ML. I'd rather wait a little
before bothering the devel list... 

Core was generated by `/usr/sbin/asterisk -f -U
asterisk -G asterisk -vvvg'.
Program terminated with signal 11, Segmentation fault.
