What is yout LabVIEW version. I have tried 7.0 and 7.1 and can confirm that the output is clipped to 10000. Your x-input must very close to 1 if you see clipping with d.o.f. of 408. What is your x input?
(even with x=0.999999, I need a d.o.f. of about 9000+ to see the clipping.) This is not good. Have you reported it to NI as a bug?
