Assume I have all of the physical RAM I need ... I want to be able to use the maximum amount of shared memory for memory mapped files. I'm guessing the largest SHM segment I can expect is 4GB .. correct??? What else competes for shared memory??? (ramdisks??? initrd???) Any help would be appreciated. Thanks, Rob
