The best way to see what kind of swap usage is going on is to use
"swapon -s", e.g.:

[root at prophead etc]# swapon -s
Filename                                Type            Size    Used
Priority
/dev/hda6                               partition       2096440 19944
-1

If swap isn't being used, try "swapon -a" to enable it, then "swapon -s"
after a while to check on it.
