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?
