[SR-Users] DRouting cause Kamailio 3.2 to stop

Hello,
finally I had the time to look at the documents you sent. The problem is
that you have recursive execution of do_routing("0") from do_routing("0").
This happens because you have route[4] like:
route[4] {
if (!do_routing("0")) {
send_reply("503", "No Rules matching the URI");
exit;
}
}
route[4] is executed from request_route. But then, in database dr_routes
table, for the prefix 961 you are using for testing, the routeid value
is 4, meaning that, when do_routing("0") is matching will execute the
route[4] from the config. Which again is calling do_routing("0") that
matches again and executes again route[4] and so on ...
At some point the OS kills kamailio, resulting in a crash reported at
random lines of code -- these were misleading so far, because at some of
them was an impossible code fault crash condition.
So, remove 4 from routeid column in the database dr_rules table.
Cheers,
Daniel
