I am trying implement the drouting... a have 3 gateway in dr_gateways table... and only one rule... gw_list=3,2,1

In the third attempt, opensips crash.... follows the configuration and mysql tables!

route{
...
#drouting
if(!do_routing("0")){
send_reply("503", "No rules found matching the URI prefix");
exit;
}

#flag 11 . flag the transaction to handle the failure route
setflag(11);
route(1);

...
}

route[1] {
# for INVITEs enable some additional helper routes
if (is_method("INVITE")) {
t_on_branch("2");
t_on_reply("2");
t_on_failure("1");
}

if (!t_relay()) {
sl_reply_error();
};
exit;
}

failure_route[1] {
xlog("FAILURE_ROUTE[1]: M=$rm RURI=$ru F=$fu T=$tu IP=$si STS=$rs RZ=$rr\n");
if (t_was_cancelled()) {
exit;
}

#drouting
if(isflagset(11)){
if (use_next_gw()) {
#xlog ("next gateway $ru \n");
t_on_failure("1");
t_relay();
exit;
} else {
t_reply("503", "Service not available, no more gateways");
exit;
}
}
}

    Hi,

    Can you please investigate the core file with gdb?
    Run 'gdb path_to_opensips_exec' 'path_to_core'' . Then run 'bt' inside and send the outout.

    Regards,
    Anca

    In GDB, frame 0, could you please print:
    branch
    request->dst_uri

    Regards,
    Bogdan

    PS : can you reproduce this crash ?
