I dont have the reference to hand but with Cisco the crash reason hinted at something very odd which was either a 
hardware failure or cosmic ray - i think it was a parity error or something similar. 

I remember this because I had such a reload and it was during a period of heavy cosmic activity.. as the hardware had 
always been reliable and was reliable after this was beleived to be the cause
