Hello,
the tls module in kamailio is using shm memory, but can be something
internal for libssl. What operating system do you use and what is the
libssl version?
Cheers,
Daniel

Hi Daniel,
I do not use puke.top rpc command. Maybe this issue related to TLS?
Servers what has this problem are utilizing TLS heavily, servers which
do not has this problem use UDP.
With kind regards,

Hello,
are you using pike.top rpc command? I noticed in the code that it
uses system malloc, but I haven't investigated further yet, first
to see if this would be a possibility ...

Hi Daniel,
We do not do any external operations.
We are using janson 2.7 everywhere. I will try to update to
latest janson version tomorrow.
All json operation is pretty much same, we are using only
jansson_get.
In attachment you can see memory consumption. On the right 2
servers which are faced internet on the left which don't face
internet. As you can see memory consumption is pretty dramatic.
Thank you for your help!
With kind regards,
Jurijs

Hello,
are you doing different external operations than on the other
instances, like mi/rpc commands.
From the list of the modules you exposed, I think jansson has
the higher probability to work with system memory. Are you
doing different json operations in config that in the other
instances of kamailio? Are you using same version of
libjansson everywhere?
Cheers,
Daniel

Hi Daniel,
This modules what we are using:
loadmodule "mi_fifo.so"
loadmodule "kex.so"
loadmodule "corex.so"
loadmodule "tm.so"
loadmodule "tmx.so"
loadmodule "sl.so"
loadmodule "rr.so"
loadmodule "pv.so"
loadmodule "maxfwd.so"
loadmodule "textops.so"
loadmodule "siputils.so"
loadmodule "xlog.so"
loadmodule "sanity.so"
loadmodule "ctl.so"
loadmodule "cfg_rpc.so"
loadmodule "mi_rpc.so"
loadmodule "dispatcher.so"
loadmodule "utils.so"
loadmodule "path.so"
loadmodule "ipops.so"
loadmodule "jansson.so"
loadmodule "auth.so"
loadmodule "nathelper.so"
loadmodule "tls.so"
loadmodule "htable.so"
loadmodule "pike.so"
We have several other Kamailio instances but they are not
faced to internet and they do not have such memory issue.
That other Kamailio instances have same modules, except
modules listed below. So if you think that issue is inside
external library, probably we need to check first modules
from list below.
loadmodule "ipops.so"
loadmodule "auth.so"
loadmodule "nathelper.so"
loadmodule "pike.so"
But maybe this other Kamailio instances do not have this
memory issue, just because they did not face to internet and
did not have same load as instances with memory issue.

Hello,
it looks like a leak from the system memory, not from
kamailio's pkg or shm memory. This can be due to an
improper use of an external library (e.g., libxml2) by a
kamailio module or because of a problem in the library.
Can you list the modules used in your config (the
loadmodule lines)? I will try to guess from the list
which one relying on external libs with higher risk of
leak issues.
Also, provide the version of kamailio you are using
(kamailio -v).
Cheers,
Daniel

Hi,
Our Kamailio server is crashing once per week, with
following error:
Oct 1 06:25:06 kamailio kernel: [26982632.803789] Out
of memory in UB 210: OOM killed process 12261
(kamailio) score 0 vm:1614768kB, rss:280200kB,
swap:131408kB
Core dump was never created, probably it is because of
my environment, but I will try to get it.
Server constantly eats memory, maybe some kind of
memory leak?
Any help is highly appreciated!
Jurijs
