Jonathan, be merciful, ECC ram last I checked is twice the cost of
regular and the mobs cost more too.  (I am sure the cost to produce is <
15% more, which makes it a great pity Intel does not standardize on
requiring it and force it to be cheap)  Some folks need to save money. 
Yeah, I know, this time it may have cost him more in cost of his time
but we are all just assuming it is memory.  Unfortunately, unless he
checks it or we see an identical error message from another user with
checked memory, or vs tells me he sees a flaw in the code, we need to
assume it is memory.

Reiser4 is more stable than the hardware it runs on.  At some point it
will be more stable than the hardware users are sure isn't the problem,
like V3 became.;-)
