Time isn't the problem. One of my servers dies at random intervals,

(cable?) or bad memory. The thing has managed to acrue enough downtime
that knocking it out for another hour or two isn't going to make an
difference.

It appears to have moved to http://sourceforge.net/projects/badmem and
it's just what I was looking for. Thanks!
