I believe it was followed by (at least) one more oops, but this one
didn't make it to disk. A couple of minutes later the box rebooted
spontaneously. I don't think this is a hardware problem since the box
is usually very stable. The box had only been up for about eight hours.
Please feel free to ask for additional information and please CC: me on
