If it truly is the kernel, then you'll need a new kernel. There are
no configuration options that would fix it. And you'll probably need
to downgrade to an earlier kernel release until the problem is fixed.
Then you can skip over 2.2.18 to a later release. That's a good plan
of attack, and at least it will tell you if it is the kernel or not.

Make sure you rebuild the modules when you change kernel versions
(they need to stay in sync). And check the international mailing
lists or newsgroups to see if other people are having problems with
release 2.2.18. If so, you can expect 2.2.19 to be out very soon.

If it's not the kernel (and it's hard to believe that there could be
such a glaring error in a stable, released kernel), then you'll need
to track down what application has the problem. Run top or vmstat and
stress the applications one by one (turn everything else off), and see
if you can find a spike in memory usage.

P.S. Y'all can now email submissions to
(like I've done with this one).
