I do some admin stuff at GMU, and while one of the other admin's here
was running it against our subnet we encountered a crash. We've got
a Paragon, and on the heavy scan it crashed during the test. We havn't
isolated why yet, but suspect that it was becasue it was being hammered
quite fast. This was after the "light & med" tests hasd passed. That
machine is fairly tight, so it wasn't a matter of there being alot
of ports open or anything... Anyway it didn't happen again, and we
really ~obviously~ arn't looking to replicate it, particlularly on
this machine, but I'd be interested to hear of any similar stuff
from other folks.
