what does /var/log/messages say?  how about the console?

i worked in an office once where a slew of unixware boxes atarted
dying.  in the end they all had the same model and revision number on
their scsi disks.  so we swapped them all out and the crashes stopped.

i'd try canceling out one of the two major variables: either use
different hardware or a different kernel.  and go nuts on the different
hardware - different cpu, different raid card, different disks.  and if
rackspace can't do that, do it somewhere else.

                         in that simplistic world-view liberals and
                         progressives are "us" and bush and bin laden are
                         "against us."
