[SR-Users] pkg mem problems. Leaking?

Hi all
I have two different kamailio servers running in a single machine. The first
one is a sl proxy and the second one acts as stateful proxy/registrar.
From time to time the stateless one goes out of pkg mem. It has 8MB (also tried
with 16 in another setup).
The sl proxy listens the public interface for external connections and the
loopback interface for conecting to the stateful proxy. As I have seen since I
installed a mem debug kamailio 3.3.2 version there 6 days ago, the internal
socket children have grown on mem usage while the external ones remain more or
less stable.
As example one uf the external udp receivers uses less than 1MB while one of
the internal ones uses almost 6MB. I'm attaching the mem dump of one of those
internal udp receiver processes via
"ngcp-sercmd lb cfg.set_now_int core mem_dump_pkg 25437" command. I see several
tens of thousands of lines like these ones:
N address=0x7fd1207383c0 frag=0x7fd120738390 size=56 used=1
alloc'd from <core>: parser/parse_param.c: parse_params(539)
start check=f0f0f0f0, end check= c0c0c0c0, abcdefed
I have no idea about how to continue debugging this. I'm pasting some more
info regarding the process list, mem status and kamailio version/flags.
Thanks
