Every so often, my file server panics and reboots--which it did just a few hours ago. The saved core reports, via 'crash':

What other information from the crash dumps would be useful? The system runs a RAIDframe RAID-R across 8 1TB SATA disks with a single filesystem. It also serves as slave DNS and NTP. -- |/"\ John D.
