you're the first to report this problem.
you're running out of kernel virtual space, probably your kernel config
increases the amount of space given to other stuff and the additional space
UBC wants put it over the edge.  I would guess that reducing the value of
NBUFS or NMBCLUSTERS will make things work again.  if that doesn't work,
then send me your kernel config file and I'll take a look.
