Hello,<br><br>We&#39;re running a Kamailio 3.3.4 system, and Kamailio is slowly using more and more memory. Over a couple of weeks it will run out of system memory.<br><br>We tried to enable memory debugging doing the following, but it resulted in Kamailio not responding to any SIP packets. Would anyone have advice please on how to debug the situation?<br>

<br>1. In Makefile.defs set MEMDBG to 1 and recompile Kamailio.<br>2. In kamailio.cfg add the line:<br>#!define DEBUG_MEMORY 1<br><br>While this was running and Kamailio didn&#39;t respond to packets, it logged lots of lines like this:<br>
