So you know about 'top' and 'free' and how to determine what is
swapped out using the 'ps' command.

OK, the assumption is you are also using the big-memory kernel too.

Do you really _need_ that much swap? Normally, with that much memory,
the system shouldm't be using much (if any) swap space. With our systems
that at work stations and relatively dumb servers, we tend to have lots
of stuff cached and/or buffered, and there might be ten or twenty Megs
of unused stuff swapped out, and that's it.

Dunno - what does 'free' show?
