Found this in the system log today. The event occurred on Monday, but the system has kept running along happily without rebooting. In fact, shutting down the IPX interfaces and running ipx_configure again made IPX work just fine.
AFAIK, the system was mostly idle at the time of the Oops. I was out of the office Monday thru Wednesday, and hardly anyone else uses the box - and certainly not through IPX.
All messages were timestamed within one second.
