This is some output from vmstat -w 5, on my quiet Alpha system (no user
interaction) that has 64M of memory and is not paging:

 procs   memory     page                       disks     faults      cpu

(some disks removed to make it fit in 80 columns)

Should avm + fre not add up to the total amount of core when not paging?
These numbers have been stable during more than 20 seconds.

From vmstat(1):

       memory Information about the usage  of  virtual  and  real
              memory.   Virtual  pages (reported in units of 1024
              bytes) are considered active if they belong to pro-
              cesses which are running or have run in the last 20
              seconds.

              avm  active virtual pages
              fre  size of the free list


It is 1.5, btw. I see similar things on my VAX while compiling -current
though (too much avm + fre although the error is a lot smaller).
