I guess one could be programmed into the monitor?

I doubt it is the monitor, but those logs may give you a hint as to what as
failing at the time of the lockup. Uhm, anything being logrotated around that
time?

You did put in a ln -s for /usr/doc right?

Those messages should not be sent unless the file space hits 80% or 90%.

Qube2s typically arrive with 78% on the root partition. A couple of other
thoughts. The /var/Cobalt logs did not all rotate correctly (I posted a
message about this several months ago). I believe one of the patches fixed
that. Look at both /var/cobalt and /var/log and make sure the logs have a
matching zipped log (if it has been around log enough to have needed zipping).
