I'd love to do some testing.... The above error indicates that for whatever reason, the system couldn't page in the data it needed for a page fault. This type of error most often occurs when running a binary over NFS and having the file or the NFS server go away. It can also happen if the disk drive that it was on stops responding or has a bad block, etc. In no case does it indicate a problem with your memory, however. -DG David Greenman Co-founder/Principal Architect, The FreeBSD Project To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
