Au contraire; a syntax error in a "make buildworld" that cannot be repeated when issued again is almost always indicative of a memory error -- especially with a new out of box FreeBSD 4.7R -- and is generally considered a good memory stress test. I was rightly alerted to a memory error. I ran Memtest86, suggested by a list-member here, and indeed, one of the Kingston 512M DIMM's was acting up. I did some research; and Kingston memory appears to have known issues with the ASUS A7V333 board. I switched the DIMM with another computer, and now both run faultless again. - Mark To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
