kswapd running at 100% - Slowing down Machine

[Andrew.Bridgeman at corusgroup.com]

We currently have a problem with one of our production Redhat machines
running kernel 2.4.21-20.ELsmp. It is running really slow and i have
noticed when doing a top the kswapd process is running at 100%. I have been
running this machine now for over a year with no problems so i am not sure
why we suddenly have this issue. I have read on the net that there are some
bug fixes which address this issue but unfortunately we need to run at this
version for software compatibility on the server. Is there a way of
resolving this issue without upgrading the kernel?

Any help would be much appreciated.

Regards
