After 10 days of up-time, 1 day after the daylight 
savings time change, the system stopped up with
disk errors.

Bringing up fsck on a floppy boot three times in
a row made the problem go away.

Does anyone have an idea of what this is?

Hard drives, in my experience, barf a few times and then die.

Can anyone give me a better rule to work with here?
