SBS 03 R2 STD, WSS 3.0, and High Memory Usage

Hello,

I am runnung SBS 03 R2 STD, and have recently done a side-by-side installation of WSS 3.0 with WSS 2.0. Now, I am getting many (at different times per day) reports that say I am using too much memory. Is this normal? I have two Google wheather Gadgets on this site: Could they be causing the higher memory use?

Thank you for our time.
