How much memory is being used? Do you ever go into swap? If not,
what's probably happening is Linux is using free memory to cache data
like I/O. Linux should automatically release this memory if it's
needed by a process. So as long as you have some free memory, I'd
say don't worry about it -- but if you start going into swap and
this memory isn't released, then you might have a problem.

BTW, you're using 'ktop', the KDE front end to 'top'? If you're
concerned about memory usage, I'd definately recommend not running
KDE, X, or any other GUI stuff.
