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!
