James only has a fraction of the story there. Yes, the alpha emitter (it was radioactive boron) that had contaminated our supplier's SRAM was a serious contributing factor to the (dreaded, infamous, triggering) e-cache parity error on UltraSPARC-II that itself was a major drag on the business. No, it wasn't the only factor (there were many, sadly -- the e-cache parity error represented multiple failures at nearly every level of the system) and no, the e-cache parity error didn't alone change the fundamentals of the business -- but it definitely didn't help!
