SubjectStrange swap problem on 2.4.5

Hi all

First post so be kind.

I have a problem on a webserver with the following hardware(RH6.2
/etc/sysconfig/hwconf)

The problem is, occationally(apparently random) the system uses about 650mg
swap, keeps that swap level for about a week then slowly over the next 2-3
days drops it off. However, if I dd the swap partition to a file, the swap
goes down to what I'd call a normal level. Running strings through the file
reveils mainly apache and perl stuff.(well it is a webserver!). Nothing else
weird seems to be happening.

Any help|explanation appreciated.
