Stevenson >Organization: MIT Media Lab >Release: FreeBSD 2.1-STABLE i386 >Environment: The disk is a 2GB Quantum (SCSI) running from a PCI SCSI controller. >Description: Every few hours or days, a series of error messages about the disk (and maybe the controller) appear on the console. These messages last about 2 minutes, and then stop. During that time, user activity may freeze, but the Web server (the primary purpose of the system) seems to be running well. My preliminary deciphering of the error messages suggest something wrong with swap space (pager errors) but I can't really tell. Late last week, the computer lost power (as did most of Cambridage, Mass.) which may have contributed to the problem, which only surfaced over the weekend. Here is a complete cycle of the /var/log/messages accounting of the problem: Aug 13 06:40:26 borg login: login on ttyv1 as daniels Aug 13 06:41:30 borg /kernel: ncr0: restart (ncr dead ?).
