I had one RP on a 12K dump about 2 years ago, and the Cisco TAC
returned that information almost verbatim regarding a soft parity
error. It was a bit of a challenge trying to reword the scenario for
those up the chain why on of our core routers decided to have a fit in
the middle of the day and all you got from Cisco was "cosmic radiation
caused it." I was almost tempted to put in a request for foil hats
just to see what type of hilarity would ensue - would have been better
if it happened at the beginning of April.
