do you have a console log available prior to the crash?
By: Eldad Ran (eldadran) 2007-03-19 13:06:44

I'm affraid not, this is a production server, and usually the console is not used, and verbosety is set to zero.

what about /var/log/asterisk/messages?

That was /var/log/asterisk/messages

Is this an unoptimized build? I'm following the code flow and it looks really... impossible with what is happening.
By: Eldad Ran (eldadran) 2007-03-21 02:18:52

Asterisk was built from release 1.4.1:
Asterisk 1.4.1 built by root @ localhost on a i686 running Linux on 2007-03-07 05:37:05 UTC
I didn't touch the source code.
If you like I can send you the specific sources, so we can verify that the code is untouched, just tell me what files do you need.
By: Serge Vecher (serge-v) 2007-03-21 08:36:54

in menuselect, under compiler options, is the "DONT OPTIMIZE" flag checked? If not , you will have to rebuild asterisk (might as well go to 1.4.2) and of crash occurs again, produce a new bt.
By: Eldad Ran (eldadran) 2007-03-24 09:33:53

Done.
now we have to wait and see.

This is the last log line, then it crashed.

Crashed again this time, running version is from branch 1.4 r69470, after running for 20 days or so, about 300K calls.
By: Tilghman Lesher (tilghman) 2007-07-01 21:02:56

The version number "r69470M" tells me that you are not using clean source.  What exactly have you modified, and would it be possible to generate a crash using unaltered Asterisk?
By: Eldad Ran (eldadran) 2007-07-02 01:09:19

I've just modified the safe_asterisk script, not the compiled code:
[src]$ svn status asterisk
X      asterisk/menuselect
M      asterisk/contrib/scripts/safe_asterisk

Performing status on external item at 'asterisk/menuselect'
X      asterisk/menuselect/mxml

Performing status on external item at 'asterisk/menuselect/mxml'

Clean code, same crash.
By: Eldad Ran (eldadran) 2007-07-05 13:13:12

The only thing I can find in common with the last 3 crashes was that all channels were in an initial mute status ('m' flag), and the state is suppose to be changed to talk mode after 20 seconds which is the duration of the meetme session (using meetmeadmin unmute command from a local channel) when it crashed asterisk.
This is a very busy system which holds at least 20 meetme clients in different rooms in any given time, and all are using the very same 20 seconds of listen only mode.
By: Eldad Ran (eldadran) 2007-07-12 01:49:16

The system keeps crashing every day, did you found out why ?
By: Tilghman Lesher (tilghman) 2007-07-12 07:15:35

Please try this patch and see if it solves your crashes.
By: Eldad Ran (eldadran) 2007-07-18 03:04:29

It looks like it fixed the problem, no crashes for the last 6 days, it used to crash every day.
Thanks.
