no no no, this is the way linux works. Memory from programs that are not
accessed alot are put into the swap so that the not-so-offen-used memory
can be used by other programs or the cache to speed up everything. When
that program later access the swaped memory it will load it up and
remove some of the cache and after a while it will put it back into the
swap (dont have any numbers on how long till it will but trust linux, it
does it very good).

I wouldnt worry at all about those numbers, they are very common in 1gig
server systems and ive worked with alot of them, even 4gig mem systems
use the swap, thats what its for...

If you are worried about preformance with memory and such after all
configure you systems like this:

If you use IDE have the system disk on one IDE channel and a standalone
swap disk on another IDE channel (not master or slave way but ide0 or
ide1). For SCSI you can just put the swap on a seperate disk.
Doing this will speed up alot of stuff since linux have 100% access to
the swap when it needs too, it doesnt have to share the IO to the disk
with another partition.

Otherwise Id just say, dont worry about it... Linux knows what its doing...

hope it helps...
