The point is that one Cpu stays at 100% for all time JGR is up.
Any ideas?

Did any of you already noticed this strange behaviour?
Thanks for your help

The problem is in the intersect function that does x = as.vector(x) and
therefore transforms date vector into a numeric .
Try to:
d1 = as.character(data1) ; d2 = as.character(data2)
d = intersect(d1, d2)
data = as.Date(d)
