Hi again,
I have read about core dump and most mentioned that I have to do a backtrace to get the reason behind the crash.
As a newbie in this field am not able to generate Where do I should stand and reproduce the gdb command, all my trials resulted with 'No Stack' as below!
I did the following:
debian:/usr/local/sbin/kamailio# gdb $kamailio_binary $core_file
GNU gdb 6.8-debian

(gdb) bt full
No stack.
(gdb)
Where is my mistake?
Again if needed syslog output before Kamailio crash!

You can start kamailio from prompt directly - of course logged as root:
kamailio {parameters - including cfg file}
If you are using ubuntu - it is more tricky - first you should create root user, or may be you can start with:
sudo kamailio {parameters}
I never started kamailio using kamctrl. I am starting it through little modified init script.

Stayon, start kamailio as root means using kamctrl start?

I am working with kamailio from 3 months or so. And we use it only as registrar and load balance. All routing is done from Asterisks which are behind kamailio. I only "route" using ds_select_dst - to select Asterisk where to forward call.
I dont like signal 15 - looks like crash from wrong arguments or something alike (but same signal you will see if you manually shut down kamailio). I have no experience with module you use.
Next steps you can do are - to increase debug level, and again to look at tail, especially in moment of dial - when kamailio crashes. You can check also core dumps - how you can do it - there is discussion now about it - important thing is may be you should start kamailio as root.

Hi,
Thanks for your reply.
I have checked, and I have one question, from analyzing two points:
- 1st point is that before adding the drouting scripts no problem with kamailio and no crash, but after adding the script in the routing logic kamailio app dies
- 2nd point if I have have any wrong data in the database and try to call, I get the ("503", "No Rules matching the URI") on the x-lite
So both points doesn't mean that the problem lies in the scripts I have in the routing logic area? (Also please note that I have got these scripts after checking the kamailio doc and other google doc that applied drouting scenario using kamailio 1.5.0).
Following your advice, I have check the syslog file before and after performing the call and am getting the below
1)When I start kamailio I have the following in syslog :
an:/usr/local/etc/kamailio# kamctl start

2) When I do the call from x-lite by dialing 961222222, after few seconds I get Call Failed: Request Timeout on x-lite, and the syslog shows:

There is no error raised; So, shall I consider this as Kamailio crash and focus my search on this as you mentioned previously? Or I need help in achieving correct route script in the routing logic?
Thanks,

I suppose - kamailio crashes. You can run in console on same server:
tail -f /var/log/syslog
or you can tail file where sys logs are stored.
There - you can see some debugs, and you can check discussion about kamailio crashes and how to get dump file.
This way you will identify problem and then either you will fix your cfg file, or you can report bug.

Hi,
I am newly experiencing kamailio 3.2. I have installed kamailio and MySQL and tried the test call from 1 PC(x-lite) to another PC(x-lite) and ended successfully.
Now moving further, I have configured dynamic routing module and applied needed parameters and scripts to finally be able to start kamailio without any issue. Also I set a testing scenario in the related database tables
BUT my problem is that whenever am trying to call the predefined prefix (961) from x-lite am getting a 'calling' message on it and then request timeout where I find that kamailio has stopped running. I kamctrl start again and call 961 then get calling so I wait and kamailio stps again. Below is the script used in the routing logic and database record.
Any help to achieve a successful call is highly appreciated.
dr_gatways: 3, 1, '192.168.111.15', 0, '', '', 2, 'PC1'
dr_groups: 2, '.*', '.*', 0, 'Anyone'
dr_gw_lists: 2, '3', 'Test Call'
dr_rules: 2, '0', '961', '', 0, '1', '#2', 'Lebanon Fix'
####### Routing Logic ########
# main request routing logic
route{
if (is_method("INVITE")) {
setflag(1); # do accounting
route(4); # Call our dynamic route.
}
}
..
..
..
route[4] { if (!do_routing("0")) { send_reply("503", "No Rules matching the URI");
exit; } if (is_method("INVITE")) { t_on_failure("4"); } route(RELAY);
}
..
