Nope... Haven't rebooted in about a month (did some wiring in the office),
and, aside from the playing around I did with the routing tables today
after I discovered it broken, nothing has changed that I'm aware of.  This
machine, in its current state, has previously logged many months of
uptime, without ever experiencing problems like this.  I may have to give
it the old fastboot treatment after all...  Hopefully my NIC isn't on the
way out, either :-)

That's an interesting script, to say the least.  However, it produces
*WAY* too much output on a busy server... Even if I pipe to a file, it has
trouble keeping up.  I'll see if I can modify it to look for particulars
:-)
