System: FreeBSD current.my.domain 5.0-CURRENT FreeBSD 5.0-CURRENT #2: Mon Mar 5 20:08:25 JST 2001 root@current.my.domain:/usr/obj/usr/src/sys/current i386
>Description:
The value produced by top(1) is incorrect.
For example,
last pid: 734; load averages: 0.13, 0.04, 0.02 up 0+00:26:37 01:32:02
33 processes: 1 running, 32 sleeping
CPU states: % user, % nice, % system, % interrupt, % idle
Mem: 9044K Active, 8241K Inact, 5703K Wired, 15K Cache, 35M Buf, 40M Free
Swap: 256M Total, 256M Free
The output above was obtained on the machine with 256MB ram.
The sum of value "Active", "Inact", "Wired", "Chache", "Buf" and "Free"
seems to be too small.
>How-To-Repeat:
% top
and investigate its output.
