[SR-Users] Memory leak in 3.3.4

[David Cunningham]

Hello,

We're running a Kamailio 3.3.4 system, and Kamailio is slowly using more
and more memory. Over a couple of weeks it will run out of system memory.

We tried to enable memory debugging doing the following, but it resulted in
Kamailio not responding to any SIP packets. Would anyone have advice please
on how to debug the situation?

1. In Makefile.defs set MEMDBG to 1 and recompile Kamailio.
2. In kamailio.cfg add the line:
#!define DEBUG_MEMORY 1

While this was running and Kamailio didn't respond to packets, it logged
lots of lines like this:

Jul 22 21:32:22 hostname kamailio: : <core> [mem/q_malloc.c:369]:
qm_malloc(0x4000e008, 128) called from <core>: cfg.lex: addstr(1438)
Jul 22 21:32:22 hostname kamailio: : <core> [mem/q_malloc.c:413]:
qm_malloc(0x4000e008, 128) returns address 0x40048918 frag. 0x40048900
(size=128) on 1 -th hit
Jul 22 21:32:22 hostname kamailio: : <core> [mem/q_malloc.c:369]:

Jul 22 21:32:22 hostname kamailio: : <core> [mem/q_malloc.c:413]:
qm_malloc(0x4000e008, 128) returns address 0x400489c8 frag. 0x400489b0
(size=128) on 1 -th hit

Thanks in advance,
