asterisk users - May 2014 - Asterisk crashes suddenly

Hello friends,

I have been experienced suddenly stops for my Asterisk server, I do not why
is it happening. Asterisk's debug messages only tell me I have lacked g729
codec for translation to one peer minutes before the crashes occur

[2014-05-27 09:48:30] WARNING[15384][C-0000017c] channel.c: Unable to find
a codec translation path from (ulaw) to (g729)
[2014-05-27 09:48:30] WARNING[15384][C-0000017c] chan_sip.c: Asked to
transmit frame type g729, while native formats is (ulaw) read/write ulaw/ulaw
[2014-05-27 09:48:30] WARNING[15384][C-0000017c] chan_sip.c: Asked to

on channel SIP/20108-00000051 setting write format to g729 from ulaw native
formats (ulaw)

And it stops after a failed attended transfer between two of my SIP peers.

There are no more messages from Asterisk but I have found this message on
kern.log, messages  and syslog.1 on /var/log/:
May 27 09:48:32 pbx-thor-PE kernel: [334427.888524] asterisk[15384] general
protection ip:482a13 sp:7f335b87c898 error:0 in asterisk[400000+221000]

I am using Debian 7.5 64 bits with Asterisk 11.9.0

Thank you!

Have you checked for core dumps?  AFAIK, Debian packages create core
dumps on segfaults in /tmp(?). You could use that to further pin point
the issue, perhaps.

$ gdb /usr/sbin/asterisk /tmp/something.core
gdb> bt full

If it is reproducable, try recompiling Asterisk with debug symbols to
get a clearer backtrace of what happened.
