Yeah... that's what I thought too because it taxes the vmem subsystem.
Plus, virtual memory and address space was limited. The OP didn't
say if he was installing i386 or amd64 though -- that will affect the
mappable memory (I would hope that he's doing amd64 though for the
obvious reason that he has 6GB of RAM).
Thanks,
