freeradius, memory consumption

[Miha]

Hi,

I am using Freeradius for authorization with mysql. In my sql I have 
about 15k user entries and there si about 50 active calls all the time 
(just for information about traffic).

Now Freeradius is in production for abot 4 months and I did not noticed 
any problems (works perfect). Today I noticed that it is using around 
77% of memory. Is this normal?

Thanks!

Miha
