"Activity Monitor" and "top" both report that.

The Java app was why it got up that high. I made the mistake of
trying to kick the Java app off using Safari. That put it into some
sort of loop where it would attempt to start and fail.

How many users do you have? Both my wife and I are always logged in,
though all she runs normally is Safari and MS Entourage.

I normally have Eudora, Safari, MS Word (originally X, now 2004),
iTunes, X-Windows, and Terminal.app running. Oh, and I just started
running nfsd on the system which has some definite overhead.

I normally run with only about 15MB of my 1.5GB free. Right now my
VM size is 7.21GB.
