It has breathing room for the 800M I would prefer to make /tmp. : : Do you by any chance have more than one swap partition? MFS will only : use the *specified* swap device as a backing store. No, I have one huge 2g swap partition that I'm using as the backing store. My guess is that I'm hitting the limits for whatever algorithm MFS is using to determine it's max size.

I thought that the entire purpose of the swap-based backing store was for MFS to dump it's contents. Am I misunderstanding this correctly? --Jerry name: Jerry Alexandratos || Open-Source software isn't a phone: 703.599.6023 || matter of life or death... email: jerry@thehutt.org || ...It's much more important || than that!
