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,
Jurijs

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,

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,

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,

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!
