Regardless of that, it sounds like your situation indicates a need to
run SAR. Turn on your system accounting collection and the reports will
let you see exactly what's happening with memory, swap, HD, ... and
when. I presume that these are as good or better than the old UNIX ones
I remember.
Once you have the bullets, I'm not sure what you might shoot, but you
ought to kill *something* just for the aggravation you've been
caused! ;-)
