This is normal memory usage, the system is cacheing filesytem use and
storing it in ram.

If the usage grows at a much faster rate then become concerned.

So when does the memory ever get released. It just grows and grows and
grows. Out of 2 gigs I have 19,124k free and starting on swap 8k used.
Should I not be alarmed on this? An old UNIX guy is telling me that there is
a memory leak somewhere....
