Geoffrey,

	Our major culprit for low swap space is typically large
	processes, not /tmp.  Do a ps -ealf command and look at the
	size column.  Oracle processes will grow over time to a 
	maximum size and stop.  If this is the case, stopping and
	restarting the processes will return the swap space.  BTW,
	how far does it go down?  Do you run out?  You can expect
	the free swap to decline, but I wouldn't worry unless you are
	close to running out or actually do run out.  Use vmstat to
	check.  Hope this helps.

Allen
