Does someone see some sort of pattern in the times (from
/var/log/messages) below? I do but know not what.

And what could explain it?

Please, note that it occurs on both harddisks and on both controllers.

Something cron related? Something swap related, since there is swap
space on both disks? I think, however, that swap is hardly used:

Device          1K-blocks     Used    Avail Capacity  Type
/dev/ad0s1b        524160       16   524144     0%    Interleaved
/dev/rad2b         524160        0   524160     0%    Interleaved
Total             1048320       16  1048304     0%

I am not aware of any enormous hard disk activity at the times in the
list. The machine does: DNS, Web, Mail. Not very busy:

load averages: 0.09, 0.06, 0.05

The machine runs: FreeBSD 4.7-STABLE #11: Wed Jan 8 00:25:26 CET 2003.

The motherboard (ECS Elite P6FX2-A for dual pentium pro, 440FX
chipset) has been complaining about ata for a long time (with slightly
different wording in the past, but I guess that was a change in the
code). But it gets more frequent now.
