Subject:   Leaks - how to find
Message-ID:  <199705091550.IAA10867@hub.freebsd.org>

Can anyone give me information on how to read this output
from vmstat -m. I saw a post about trying to find leaks
using this command. I have set up a new FreeBSD box
version 2.2.1-release. I'm new to the Unix world. After
a couple days my free memory seems to dissappear. I'm
starting an ISP and I'm testing the box before I go
live. I guess I'm just asking what to look for as a sign
to find my culprit. This output is after 9 hours of up time:
