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

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 Apr 24 15:08:53 vm-tkamasy1 /usr/local/sbin/kamailio[2795]: WARNING: fm_status: summarizing all alloc'ed. fragments: Apr 24
