Maybe I have a very naive view of the VM structure, or maybe I need more coffee, but my brain is having a hard time here. If you're using a lot of swap then presumably it's because you don't have a lot of free RAM, so paging out the contents of RAM into other RAM makes me uncomfortable, because what happens when you run out ? Mind you, I suppose you could also run out of swap on disk as well, and that's probably what you're saying isn't it, and I wonder how deep I can make this hole now I've started ... OK, I think I see your point. ;) (although if that wasn't it then let me know please!)
