[c-nsp] 3825 memory issue

[Tseveendorj]

Hello,

I'm using 3825 router to provide internet for ADSL customers. Last week 
I configured policy-map to provide different bandwidth usage. Since this 
time my routers memory usage goes up.

2. Is there any unknown process working ?
3. How do I decrease memory usage ?
4. What is column of memory real usage ?

Sincerely,
Tseveen.
