Hello All,
I'm load testing Kamailio with siptrace (duplicate) enabled, but for some
reason not all SIP messages are arriving at the sip capture server (kamailio
instance with sipcapture).
The load is an average of 50 CPS.
I enabled debug 9 and I get the following messages.
<core> [mem/q_malloc.c:369]: qm_malloc(): qm_malloc(0x7fefde4da010, 1274)

In siptrace.c I see the following line of code:
if(ps->flags&TMCB_RETR_F) {
LM_DBG("retransmission\n");
return;
}
Does this in fact retransmit the message to the capture server?
Has anyone else load tested kamailio with siptrace on?
I'm using Kamailio 4.1. I'm also using the setflag(..) function in siptrace
module to duplicate all forwarded messages to the capture server.
Regards,
Grant
