The topic of sunspots is certainly familiar from long ago. We had a 7513 that crashed unexpectedly, upon a review of the data available, it was determined that a parity error had occurred. I can't remember the exact error as it was several years ago, but upon a quick search this article seems familiar.

Search on cosmic radiation and/or SEU within.

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. Andy
