Not encouraging. Is this a major problem, or just a case where the kernel
screwed up, caught it's own error, and went merrily on? I disabled swap
and re-enabled it, and the messages stopped. This was on a year old ISP
shell/mail server (AIR board, P90, 96mb RAM, NCR 810 and aha-1540cf, SCSI
disk/tape, some old VGA board...sometimes even a monitor), 16 or so users
logged in. The only process of note was the nightly system backup had
begun about 20min before the messages started.
