    sys/kern             vfs_subr.c 
  Log:
  Make the maximum number of vnodes a function of both the physical memory
  size and the kernel's heap size, specifically, vm_kmem_size.  This
  function allows a maximum of 40% of the vm_kmem_size to be used for
  vnodes and vm objects.  This is a conservative bound based upon recent
  problem reports.  (In other words, a slight increase in this percentage
  may be safe.)
  
  Finally, machines with less than ~3GB of RAM should be unaffected
  by this change, i.e., the maximum number of vnodes should remain
  the same.  If necessary, machines with 3GB or more of RAM can increase
  the maximum number of vnodes by increasing vm_kmem_size.
