What were you doing, and what did you notice when the problem started?

As much as it seems silly, I'm mostly interested in what your network 
was doing at the time things went sour.

For some reason, and with no explanation or science behind it, I don't 
think this is a ZFS problem, and I'm trying to defend this thought to my 
peers until I prove otherwise.

I have to be a bit careful on how I adjust loader properties, given that 
I'm loading from USB, and mounting root from a ZFS zpool hard disk. Like 
my GELI systems, tweaking things can be a bit touchy unless I put a 
little more planning into it.

I'm not a hardware person per-se, but I'm advised to post that the 
motherboard is:

- XFS nForce 610i with GeForce 7050

If there is more hardware info I can provide, let me know specifically 
what I should be looking for.

zpool status is always clean. There are no errors otherwise, even if the 
box is up for multiple hours straight. The problem occurs only if I 
through work at it.
