You're using a DNS resolver or coming from a network that's facebook
blessed. Note the difference:
server:# dig www.facebook.com @ordns.he.net +short

I think the simple test for this problem is to take a non-ECC machine, boot
from a CD/USB Key/etc with memtest or memtest86+ on it, and see if you get
errors over the course of a few days.
Getting errors will certainly prove that this problem exists (or that you
have bad ram).

Let's just assume you have enough disk space that you can write out

With RAID 4, the parity disk IOPS on write will rate-limit the whole LUN...
No big deal on a 4-drive LUN; terror on a 15-drive LUN...
