Hi all
I have a box with Centos 4 and qmail with all pathches. since Last
month
i
have had twice the same problem. The process kswapd0 uses all my
resources
of CPU and RAM memory and the consequence is that my local queue
grow up
and
the box go slow too.
The first time i guess the problem was the version of the kernel,
so i
did
an upgrade form kernel.i686 2.6.9-5.0.3.EL to kernel.i686
2.6.9-5.0.5.EL
apparently the problem was solved but today the problem came again.

following snapshot shows the situation:

I think this bug is your problem:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=150971
You can try the kernel at:
http://people.redhat.com/davej/kernels/RHEL4/RPMS.kernel/
(or I can give you version 2.6.9-6.37.EL that is in 4Update1 beta)
Hi Mr. Hughes
The kernel version 2.6.9-6.37.EL has known issues
That is the only other one I have for EL4 (other than the released kernels).
Maybe the 2.6.9-10.EL then ... but that is pretty new ... he just made it yesterday :)
Hi again Mr Hughes
So sorry but i forgot the question mark :S
I really want to know if this kernel has known issues (The kernel version 2.6.9-6.37.EL has known issues?)
regards Mario

OK ... got it :)
The 2.6.9-6.37.EL kernel is supposed to fix the memory bug that I pointed to earlier. The 2.6.9-10.EL kernel is also supposed to fix that issue.
As to other issues, I am sure there are some ... but none that I know about.
