Gradual increase in memory usage

15 Jan 2014

      Hello everyone

I have an instance of FreeRADIUS which is gradually consuming memory. The
version is as follows:

radiusd: FreeRADIUS Version 2.2.4 (git #b15a660), for host
x86_64-unknown-linux-gnu, built on Dec 27 2013 at 12:46:27

I ran it in valgrind but I am not sure how to interprete the output:
