This page logs instances of dead machines; we are using it to track down the mysterious machine crashes occurring in September/October/November 2011.
NB: As of 7.11.2011 the infiniband stacks (OFED) have been removed from rc01-rc20. Let's see if the IB drivers are causing the problem.

- September 28: rc04, rc19, rc20, rc21, rc25, rc26
- rc04 was powered off
- rc19/20 appears to have a bad power supply
- rc21 was at Linux login prompt with cursor blinking, but didn't respond to keyboard
- rc25/26 was not plugged in (oops)
Notes
Nov 7th: Trying to see if OFED stack is causing the problem by removing it on rc01-rc20. Why the lower 20 are overrepresented compared to the upper 20 I don't know.
