Summary:                    Asterisk crashes with segfault message two or three
times a day
Description: 
Hi,

sometimes our Asterisk-Server crashes unexpectedly, but I don't know how
to reproduce the situation. 

While crashing, I always get the exact same message in /var/log/messages:
Mar 24 09:28:35 PBX-ZRH kernel: asterisk[13553]: segfault at
0000000000000288 rip 00002aaabc54db94 rsp 00000000419ca918 error 4

This happens two or three times per day.


Last line before the crash in /var/log/asterisk/messages:
[Mar 24 09:28:34] NOTICE[13553] rtp.c: Unknown RTP codec 126 received from
'0.0.0.0'

And after the crash in /var/log/asterisk/messages:

I used yum to install Asterisk, and I have automatic updates configured
via yum, too.
