I suppose you could boot it, get "top" running and keep an eye on it
to see if something takes over and starts running roughshod over your
IO, memory, processor when the box becomes unresponsive.

For example, at one time I had a spamassassin setup that was trying to
resolve DNS for each message and it would drive the load into double
digits and nearly lock the box up until it made it through the batch
of mail.
