Even with PAE and 64GB of RAM, there's a physical limit on what a process can address, 4GB, and that's further limited by resources that must be mapped into the process space. IIRC, the number is more like 3.3GB or thereabouts, depending on the build and hardware. Unless, of course, they're specifically coded to make use of PAE... :) -- Ross McKay, Toronto, NSW Australia "My old man told me one time, you never get wise, you only get older" - Dandy Warhols -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
