Re: kernel leaking memory somewhere

By the way, a good way to find out if you're running low
on RAM is to watch the output from "vmstat 5" for a while.
(Ignore the first line because it contains the values
since reboot.)

In particular, if the "po" (page out) and "sr" (scan rate)
columns stay at zero most of the time, then there are no
problems.  The "scan rate" is a good way to measure the
memory pressure that Matt explained.

(Don't worry if the "pi" (page in) column is non-zero,
because it includes normal system activity such as reading
pages from memory-mapped files.)
