This has been an issue with a server in our school. It is a thin client server for 40 boxes and has 2 gigs of ram. The cached/buffered ram climbs for two days until the system slow-down is VERY noticable. Everyone says that ram will be freed up when needed, but by the constant slow-down until reboot, it doesn't seem to work. The only option is to reboot every two days.
So as Rigo mentioned " just don't worry about it unless you are having slowdowns"... This is what is happening. We are having intollerable slowdowns. Is it a kernel problem, or is there something that I can change in a configuration file to free up this ram?

I have noticed that the memory usage keeps going up. I am using this machine as a server so it never shutdowns, and reboots very rarely. When I do reboot it, it is using about 100M of memory out of 512M. This is according to TOP. Currently the machine has been up for 21 minutes and the memory usage is already at 147M. How can I figure out what is taking the memory?
linux uses memory as cache. just don't worry about it unless you are having slowdowns. You don't have to worry about it because the memory is going to be freed when you need it.
