Public bug reported:
Binary package hint: asterisk
We are getting occasional segfaults on a karmic system
(1:1.6.2.0~rc2-0ubuntu1.1) with heavy iax2 traffic (crashes occur every
few days):
[442046.620342] asterisk[8552]: segfault at 48d ip b6022c71 sp b4ee04a0
error 4 in chan_iax2.so[b5ff2000+48000]
A backtrace reveals:
Core was generated by `/usr/sbin/asterisk -f -p -g -U asterisk -vvvg -c'.
Program terminated with signal 11, Segmentation fault.

This bug was reported as part of another bug report in the Asterisk
issues system (https://issues.asterisk.org/view.php?id=15609#111024) and
fixed in both the 1.4 and 1.6.2 lines (the patch is the same for both
lines):
http://svnview.digium.com/svn/asterisk/branches/1.6.2/channels/chan_iax2.c?view=patch&r1=219590&r2=219589&pathrev=219590
Please consider applying this patch, as it is causing Asterisk-wide
crashes. Thank you.
