If vmstat is run just after booting values are reasonable, but after a large memory process is started, avm goes wild. vmstat -c2 5 procs memory page disks faults cpu r b w avm fre flt re pi po fr sr fd0 wd0 da0 in sy cs us sy id 0 0 0 3688664 7128 10 0 0 0 10 2 0 0 0 235 94 10 14 1 86 0 0 0 3688664 7128 1 0 0 0 0 0 0 0 0 231 9 4 0 0 100 A check of the values returned by sysctl are strange: vm.vmmeter: Format:S,vmtotal Length:48 Dump: 0x0200 t_rq 0000 t_dw 0000 t_pw 0b00 t_sl 0000 t_sw 0000 (Fill, not used) 6a4e1180 t_vm 41140e00 t_avm e3170000 t_rm 08050000 t_arm dd0b0000 t_vmshr f8020000 t_avmshr 78030000 t_rmshr 54010000 t_armshr 91060000 t_free given that I only have 192M of swap or so and 32M of real memory, the value of t_vm and t_avm seem more than a little large.
