Brian's XServe is acting up, and we're trying to figure out wtf went wrong, and trying to work with his IT folks that are managing the box for him.
In our quest for answers, I came across these resources (which have been dutifully bookmarked, delicioused, and added to my DevonThinkPE cache). I'm adding them here as well...
They're trying to round up a hardware diagnostic CD to check RAM, motherboard, etc... Here's hoping for good backups...
UPDATE: Looks like it was a stick of RAM that decided to go south. Hopefully the many power cycles and reboots didn't scramble any data...
