Hello Pawel,

maybe you've already tried this. But have you recompiled on a test system with 
memory debugging enabled in the Makefile.defs and then a proper memlog 
parameter in the cfg file set? 
http://www.kamailio.org/wiki/cookbooks/3.3.x/core#memlog

Then you could execute the code in question and see if after N executions you 
see N times the memory allocated. The output of the command and how to get it 
is described here 
http://www.kamailio.org/dokuwiki/doku.php/troubleshooting:memory
you should be able to see the place in the code where its allocated (and 
probably not freed).
