### 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
