This 4GB process space limit is a user space process limit. There is no limit on the kernel itself. A PAE enabled kernel can directly use all 64GB of RAM for its own needs, i.e. for page/buffer cache, ramdisk, etc. -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
