[RADIATOR] Radiator & Debian Wheezy = memory problem?

[Michael]

- i use SessionDatabase NULL to disable this feature.
- my radiator service handles many different authentication methods and 
my config is quite large.  i'm up to 6,043 lines of config.  I don't 
wish to send the config to anyone.
- not sure what the logs are going to show for this mater not to mention 
what part of the logs would anyone want to look at.
- i didn't say it was a memory leak.  I just responded to Kurt Bauer 
saying that I experience the same problem ie. Debian Wheezy and 
increased memory usage over time.
- i'm not actually looking for help though.  I do realize how hard it 
would be for someone to help via email on such a matter.  thanks anyways 
though.
