+1 on hardware issues...I won't name names, but once recently I ordered 
two identical systems and I had to send one of them back FOUR times: two 
bad raid controllers, bad ram, and bad motherboard. This was all started 
about 4 weeks into production. I don't know if the vendor was actually 
doing burn-in, but I've seen pleny of damage from shipping. Do your own 
memory testing and line up another (nearly identical) server to verify 
the problem.

Good luck,
