[asterisk-users] asterisk crash and core dump: format_mp3.so
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. #0 0xb7b41954 in ?? () from /usr/lib/asterisk/modules/format_mp3.so (gdb) bt #0 0xb7b41954 in ??

You should check bugs.digium.com and if it's still valid for 1.4, you should post your backtraces there. As solution - we refused from using format_mp3 at all - actually it has almost no benefits. If your MOH is in MP3s - you will get them decoded (and translated to necessary codec) on-the-fly for every call, so more performance. You can convert all your MOH to native channell formats of asterisk, and put all those files (one for each format/MOH combination) in MOH directory - asterisk will pick up one with less translation.

Actually, I'm using 1.2.21.1 so since 1.2 will only receive security fixes I don't think I'll post a bug report.

[asterisk-users] asterisk crash and core dump
My Asterisk installation crashes frequently. Since it's a random event I am not able to reproduce it so I can't say what is making it crash. Here's a snippet of /var/log/asterisk/full just when it crashes: Sep 18 13:42:51 DEBUG[378] chan_zap.c: disabled echo cancellation on channel 31 Sep 18 13:42:51 VERBOSE[378] logger.c: -- Hungup 'Zap/31-1' Sep 18 13:42:51 DEBUG[32650] chan_sip.c: Stopping retransmission on '[EMAIL PROTECTED]' of Request 102: Match Found Sep 18 13:42:52 DEBUG[32677] manager.c: Manager received command 'Command' Sep 18 13:42:52 DEBUG[32677] manager.c: Manager received command 'Command' Sep 18 13:42:52 DEBUG[32677] manager.c: Manager received command 'Command' Sep 18 13:42:54 DEBUG[32650] chan_sip.c: (Provisional) Stopping retransmission (but retaining packet) on '[EMAIL PROTECTED]' Request 102: Found Sep 18 13:42:54 VERBOSE[419] logger.c: -- SIP/4002-082aef20 is ringing ---MESSAGE FROM SAFE_ASTERISK--- Automatically restarting Asterisk.

You'd have to get an Asterisk developer to look at the backtraces generated from those core files. There's more information on the backtraces either in doc/backtrace.txt in the Asterisk source, or at the following URL: http://svn.digium.com/view/asterisk/branches/1.4/doc/backtrace.txt?revision=46298view=markup If you're able to get some good backtraces, grab one of the Asterisk developers on the #asterisk-bugs channel in IRC (on the Freenode network) and they'd be happy to try to help you figure out the cause of your crashes. -- Jared Smith Community Relations Manager Digium, Inc. ___ Sign up now for AstriCon 2007!

You should compile asterisk with debbuging enabled (and optimization disabled), and then take backtraces from core dumps.
