I know, but as our load has increased, so has the frequency of the
crashes, which after much disabling of almost every cronjob and
process on the box has lead me to believe that it's Apache that's at
fault.

I'll give memtest86+ a go and see what that reports; hadn't thought of
physically testing the memory; I've already had the drives replaced in
case it was that...
