The original status code (270001) is "Undefined VME Interrupt."  While there
are probably lots of ways to get this, I saw most of them when our power
supplies were flaking out.  After you have a crash, take the right-hand side 
(as you face the machine) off, and check the LEDs on the power supply (the bottom
board in the X-bus).  There should be a handy interpreter's guide to the LEDs on
or near the supply board too.  If you have 5V or 12V undervoltage, you will soon
need a new supply.  You might want to take the board out, remove the slide-in
power bricks, and clean the contacts (some people have had good luck with this).

If you have more than one memory board, you might want to pull the board in 
slot 7 and try again.  If things succeed, then you really do have a bad RAM board
(this doesn't explain the 270001 status though).
