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, Jurijs On Thu, Oct 6, 2016 at 5:17 PM, Daniel-Constantin Mierla &lt;miconda(a)gmail.com <mailto:miconda@gmail.com>> wrote: 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?
