[SR-Users] siptrace retransmission's

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) called from siptrace: siptrace.c: trace_send_hep_duplicate(1615) <core> [mem/q_malloc.c:439]: qm_free(): qm_free(0x7fefde4da010, 0x7fefde618a88), called from siptrace: siptrace.c: trace_send_hep_duplicate(1659) <core> [mem/q_malloc.c:439]: qm_free(): qm_free(0x7fefde4da010, 0x7fefde61ee18), called from siptrace: siptrace.c: trace_send_hep_duplicate(1660) <core> [mem/q_malloc.c:474]: qm_free(): qm_free: freeing frag. 0x7fefde61ede8 alloc'ed from siptrace: siptrace.c: trace_send_hep_duplicate(1615) <core> [mem/q_malloc.c:369]: qm_malloc(): qm_malloc(0x7fefde4da010, 1271) called from siptrace: siptrace.c: trace_send_hep_duplicate(1615) <core> [mem/q_malloc.c:439]: qm_free(): qm_free(0x7fefde4da010, 0x7fefde61b488), called from siptrace: siptrace.c: trace_send_hep_duplicate(1659) <core> [mem/q_malloc.c:439]: qm_free(): qm_free(0x7fefde4da010, 0x7fefde61e880), called from siptrace: siptrace.c: trace_send_hep_duplicate(1660) <core> [mem/q_malloc.c:474]: qm_free(): qm_free: freeing frag. 0x7fefde61e850 alloc'ed from siptrace: siptrace.c: trace_send_hep_duplicate(1615) DEBUG: siptrace [siptrace.c:1040]: trace_onreq_out(): retransmission DEBUG: siptrace [siptrace.c:1040]: trace_onreq_out(): retransmission DEBUG: siptrace [siptrace.c:1040]: trace_onreq_out(): retransmission DEBUG: siptrace [siptrace.c:1040]: trace_onreq_out(): retransmission DEBUG: siptrace [siptrace.c:1040]: trace_onreq_out(): retransmission DEBUG: siptrace [siptrace.c:1040]: trace_onreq_out(): retransmission DEBUG: siptrace [siptrace.c:1040]: trace_onreq_out(): retransmission 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.
