For what it's worth, Facter itself is unlikely to be crashing your system, but it runs a variety of commands that probe system details, and it's possible that one or a combination of those sometimes crashes them. It should be possible to crash the systems by running the same commands from the shell. If you have straces of facter sessions that resulted in crashes then they might be illuminating. The key thing I would be looking for is what commands Facter is trying to run when the crashes occurred. Unfortunately, the nature of the problem precludes being certain that the last thing in the captured trace is actually the thing Facter was trying to do when the crash happened. If there is a software bug then it is probably in a separate tool or in the OS kernel. It might also be that you have a firmware (i.e. BIOS) bug on the affected systems, or even that the particular motherboard model that is affected has a design or fabrication flaw.
