I'm using 6.0.2.0. Your third argument is invalid. The third argument
should be the LENGTH of the number, to the BASE (10 in this case). As
to using Pi, use N[Pi] to have it evaulated as a REAL number first. In
otherwords try this instead:

RealDigits[N[Pi].10,10^4]

I can't go beyond 10^4 as a LENGTH, due to memory constraints, on my 1
GB of RAM sytem!
