But I'm not sure how many users have such large CMS disks?
Hi, Jan. I'm going to have to agree with Mark and David that the idea of messing with memory overcommit and the ulimits in order to get a file system to function is a non-starter. It's too complicated. If you want to using memory mapping, that's fine, I guess, but it needs to map a much smaller "window" on the disk and move the window around as needed.
