How long have those machines been online?
There is a discussion about the 2.4.21rc kernels on the SE Linux mailing list.
Machines running 2.4.21rc kernels seem to have a kernel memory leak which
makes them unusably slow. Opinion is divided on whether this is a kernel
issue or a SE Linux issue. I don't believe that it is SE Linux at fault as
the SE code we are using is a straight port from 2.4.20 (and should run
equally well as on 2.4.20). However other people have seen some evidence to
suggest that the problem may only occur on SE Linux machines (I don't run any
non-SE machines at the moment for testing).
I would like to see some more data-points about the reliability of 2.4.20-rc
