[SR-Users] DRouting cause Kamailio 3.2 to stop

Fri Feb 24 16:04:47 CET 2012

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.
