Well, *all* of these are rackmount servers, with no moving-the-server
wear. We start seeing userspace compute-intensive processes crashing the
system a number of times a day. We have a canned package that we send to
Penguin on the disk we put in, which has a generic CentOS install, and
running that, the crash is repeatable. They replace the m/b, and it
doesn't happen again. (Or at least with that program - we've got issues
with some *other* users, with different software, that seem to be crashing
it. With us, this is seriously important, since the users' jobs run for
days, sometimes a week or more, on the cluster....
