[SR-Users] Kamailio crashes after Contact expires event route

[Sergiu Pojoga]

Hi there,

After below even route is triggered, Kamailio crashes with the following in
logs:

Feb 12 08:03:59 kamailio[24671]: INFO: <script>: Received HTTP/RPC request
from IP=127.0.0.1
Feb 12 08:03:59 kamailio[24671]: WARNING: <script>: Contact
myusername at sip.mydomain.net has expired
Feb 12 08:03:59 kamailio[24671]: INFO: drouting [drouting.c:483]:

event_route[usrloc:contact-expired] {
   xlog("L_WARN", "Contact $ulc(exp=>aor) has expired\n");

   # Remove the sip: from the front of the Received URI
   $var(exp_received) = $(ulc(exp=>received){s.substr,4,0});

  sql_query("db", "UPDATE `dr_gateways` SET address = '127.0.0.1' WHERE
address = '$var(exp_received)'", "rz");
  sql_result_free("rz");

  jsonrpc_exec('{"jsonrpc": "2.0", "method": "drouting.reload", "id": 1}');
}

If I comment out the sql and jsonrpc_exec lines above - crash does not
happen.

Let me know if core dump is needed.

Thanks,
--Sergiu
