Hello,
do you get errors like "pv_sprintf: ERROR: wrong format ..." from perl
module? It looks like a leak in this error case.
If not, can you compile with MEMDBG=1, then set memlog in config less
that debug and run/test it for a while?
Restart it and look at the logs at shut down to spot any memory leak.
You can send it to me if you want me to analyze them.
I recommend you set children=2 or 4 to make the leak faster visible.
Also, you can decide what types of stats you want via:
http://www.kamailio.org/wiki/cookbooks/4.0.x/core#mem_summary
You can use value 12 to make the output more compact.
Cheers,
Daniel

Hello,
what version are you running? Is it after the commit:
http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=341f810dca0cc0596e22f2ac1bca86de0b8d142d
?

Hello
We've put Kamailio on a machine with a SIP-Proxy role, we replaced
another SIP proxy implementation.
We started with the default 4Mb of PKG Memory and 1024 Mb of Shared
Memory but we had messages like these in the logs:
2013-09-26 13:48:26,939 ERROR: app_perl [kamailioxs.xs:371]:

build_res_buf_from_sip_req(): ERROR: build_res_buf_from_sip_req: out
of memory ; needs 376
Then we started kamailio like below, with 1024Mb of private memory
(per process) :
/opt/kamailio/sbin/kamailio -f
/opt/kamailio/etc/kamailio//kamailio.cfg -w
/opt/kamailio/core_dir/corefiles -P
/opt/kamailio/var/run//kamailio.pid -m 1024 -M 1024 -u kamailio -g
kamailio
Then after about 4 days we realized that we have a steady increase of
used memory ( in the output of free command the '-/+ buffers/cache:'
row ), and we simply restarted the kamailio process.
The machine has 12 Gb of RAM , we run with children=32 . 1gb of
memory per process x 32 child processes means that we are over the
physical capacity of the machine.
The question is , are we in any danger of running out of memory on
this box where we only run kamailio ? We don't want to reach the
point where the kernel starts killing processes.
Shall we suspect some memory leak in the app_perl module ? (we do
some http queries over SSL from a perl script)
Thank you.

Dragos Oancea
