From the list of the modules you exposed, I think jansson has the higher

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 version: kamailio 4.4.3 (x86_64/linux) 5a2195 flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: 5a2195 compiled on 08:30:51 Sep 15 2016 with gcc 4.4.7 With kind regards, Jurijs On Thu, Oct 6, 2016 at 12:52 PM, Daniel-Constantin Mierla &lt;miconda(a)gmail.com <mailto:miconda@gmail.com>> wrote: 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).
