### Description
Kamailio is crashing every 2-3 calls with this sample config. I dont mind paying for a
paid support. Please help :)
Ive used asterisk server to generate calls like
```
for i in `seq 1 4`;do asterisk -rx'originate Local/1@test application
MusicOnHold';done
extensions.conf:
[test]
exten => 1,1,Set(CALLERID(all)=12345)
same=n,Dial(SIP/q_1_Test_Queue@1.1.1.1:5060)
request_route {
# MOH queue?
if ($rU=~"c_" || $rU=~"q_") {
if (mohq_process ()) {
if (is_method("INVITE")) {
route(ACCSTART);
xlog("L_INFO", "QUEUE JOIN: $ci $rm from $fu to $rU/$ruri
(IP:$si:$sp)\n");
}
exit;
}
}
}
route[ACCPREPARE] {
$var(callid) = "$ci";
$var(referCallid) = "";
$var(did) = "$rU";
$var(clid) = "$fU";
}
route[ACCSTART] {
route(ACCPREPARE);
xlog("L_INFO", "ACC START: did $var(did) didid $var(didid) action
$var(action)-$var(value) valueid $var(valueid) trunk $si:$sp\n refered-by
$(hdr(Referred-By))");
}
```
### Troubleshooting
