Hi!
We are using the t_uac_dlg function through a UDP MI Datagram to create local
SIP/TCP requests. We are seeing a memory leak of increasing shared Memory
usage, which is increasing at the same rate as tcp connections are created
(tested under 4.0.1 and 4.3.1).
/usr/sbin/kamailio[25407]: NOTICE: fm_status: count= 71943 size= 14126536
bytes from mi_datagram: datagram_fnc.c: build_async_handler(387)
After looking at the memory dump and investigating the source, I guess that the
memory leak is created, when the
MI_ASYNC_RPL_FLAG
is set. This seems to be set by:
modules/tmx/tmx_mod.c: {MI_TM_UAC, mi_tm_uac_dlg, MI_ASYNC_RPL_FLAG, 0,
0 },
only, which we are using heavily.
Can someone please give me a hint, where to search for the memory leak. My
guess is that:
modules/mi_datagram/datagram_fnc.c:489
if (f->flags&MI_ASYNC_RPL_FLAG) {
hdl = build_async_handler(mi_socket_domain,
(struct sockaddr* )&reply_addr,
reply_addr_len);
the handler is not correctly freed up in the async reply case.
Thank you!
Greetings
Torge Szczepanek
