even without any additional modules in use radiator will of course use
some memory. Features like the session database will gradually build up
memory usage until a level that matches your workload is reached.

Restarting radiator will of course free up all of the memory.

This would not be a memory leak but legitimate usage that you have to
account for to match your workload or number of concurrent sessions in 
the case of session db.

If you have a memory leak the process size would grow without ever
reaching a saturation point.  To find out if it is so you need to watch
memory consuption with a graphing tool mrtg/cacti/observium/....

If you see a graph that slowly saturates alls fine. If you see steady
growth investigate further.

Greetings
Christian
