vmstat displays avm and fre alltogether:
# vmstat
procs memory page disks faults cpu
r b w avm fre flt re pi po fr sr da0 da1 in sy cs us sy
id
0 0 0 5404197860 1 0 0 0 1 0 0 0 152 10 3 0 0
100
this makes some monitoring programs go crazy
>How-To-Repeat:
type vmstat in a command prompt, look at the output
>Fix:
possible fix is:
