Re: [SR-Users] 4.4.5 Shared memory leak with t_suspend/t_continue

25 Apr 2017


      Hello,
I found my mistake!
Transaction has been suspended in request route, and i try to_continue from
 onreply route.
I change the scenario:
- receive INVITE
- reply and suspend
- in onreply route (when received 180)  send  OPTIONS to localhost with
$T(id_index):$T(id_label)
- in request OPTIONS, continue transaction with adding a new branch.
*Memory leak does not happen.*
*Question:*
Is it possible to revoke the suspension of the INVITE from the script
(without adding a "fake" branch),when received reply is 183?
Thank you,
Julia.

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
