This happened on my server two nights ago (solid machine: Asus P3B-F
board, not overclocked, Kingston ECC RAM, Adaptec SCSI controllers,
Enermax 430W Power Supply):
The box was building a giant tar file on a temporary holding
disk so it can be dumped onto the attached DLT-8000 drive (like
it does it every night). Today I discovered that it had crashed
during this process. Last night everything went well again (as it
did for the last years as well :-).
