Hello Daniel,
Thank you for reply.

I haven't used event-route in this scenario.
When i fork parallel (without suspend/continue), memory leak does not happen.

Hello,

there seem to be quite a lot of avps -- are you using an event_route block with avp variables inside?

Cheers,
Daniel

Hello all,

I need to fork an incoming call to the second destination, after receiving 180 reply from the first destination.
I use kamailio version 4.4.5
It working fine, but with shared memory leak.
The script part:

       $avp(00x)=$_s(sip:$var(00x)@$si:$sp;user=phone);
       if(!is_known_dlg()){
                dlg_manage();
        }
        t_relay();
        append_branch("$avp(00x)");
        if(t_suspend()) {
                xlog("L_NOTICE","FORK: suspend transaction[$T(id_index):$T(id_label)]\r\n");
        }

onreply_route [REPLY_TO_SOURCE] {
if ($T_reply_code=="180") {
t_continue("$T(id_index)", "$T(id_label)", "RELAY_FORK");
}
}
route[RELAY_FORK] {
                $ru=$avp(00x);
                $avp(tu) = $_s(sip:$rU@$td;user=phone);
                uac_replace_to("$avp(tu)");
                remove_hf("Supported");
                xlog("L_NOTICE","RELAY_FORK : $rm CSeq[$hdr(CSeq)] branch[$T_branch_idx]\r\n");
                t_relay();
}

Please find the result of  kamcmd corex.shm_summary after 300 calls
