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 ...
Cheers,
Daniel

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.
kamailio -v

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
