[SR-Users] Segment fault

[Nick Raper]

This is our call forward route:

route[CALLFWD]
{
        if(!is_method("INVITE"))
                return -1;
        if($avp(DST_CARRIER) != CARRIER_US)
                return -1;
        sql_result_free("ra");
        sql_query("ca",
                "SELECT forward, fwdnumber FROM subscriber WHERE username='$rU'",
                "ra");
        if($dbr(ra=>rows)<=0) {
                return -1;
        }
        if($dbr(ra=>[0,0])==1) {
                $rU = $dbr(ra=>[0,1]);
                $avp(ACC_FWDNUMBER)=$rU;
                return 1;
        }
        return -1;
}

How do you load the value of fwdnumber and then how you use it to update the request uri?

The backtrace points to an assignment, but I need to know exactly the operations you do to track it down.

Cheers,
Daniel

I see now that we had an entry in the 'subscriber' table with forwarding enabled but the 'fwdnumber' field was blank.

Could this be the cause?

Hello,

according to the log, you got a coredump:

Jul  1 14:44:52 sipa /usr/local/sbin/kamailio[2837]: ALERT: <core> [main.c:754]: core was generated

Send the output of 'bt full' taken with gdb from the core file -- the core file is either in / or in the working dir of kamailio.

Also, mention the version of kamailio that you are using (kamailio -V).

Cheers,
Daniel

Hi,
