I am not sure if you got my reply to this Alan, but I would like to
have you send me the patch. Thanks.

Also, I got to thinking back and it dawned on me that there was
another significant kernel change when we started experiencing the
freezes from the vm problems. We changed the compiler from
gcc-2.7.2.3 to egcs-1.1.2 starting with kernel 2.4.0-test10 (That is
the version in which gcc-2.7.2.3 stopped being supported for the
kernel) and it seems like that was just about the same time frame that
we started experiencing the vm/swap problems. I would have to go back
and run on the test10 kernel for a while to confirm if it started with
it or 2.4.0.

I am assuming the source of the vm problem is still unknown or it
would have been fixed by now. Is it possible that it could be related
to the compiler change? If nobody has considered that, I just thought
I would bring the possibility to your attention.
