Sorry, I was confused; it was megs. That'll teach me to send e-mails when I'm really tired. I normally run with half that (to really stress the paging/writeback systems), and I was thinking that a gig of memory was way more than I normally use. I think I was running into some failures at 512m, which is why it got bumped to 1024. I'll have to try it again at 512 and see if it blows up or not. - Ted
