I spent a couple very stressed weeks (nights, weekends) debugging a crash that would only happen every 30 minutes or so. It looked like stack corruption, so I was trying all avenues to debug it. Nothing seemed to make sense. We finally figured out that it was a signal integrity problem on the DDR memory bus. Software was fine.

Did you see that post a few days ago about "Is ECC RAM worth it?"

The answer, after my hellish debugging is an unequivocal YES! My horrible problem would have either manifested itself as a correctable ECC error or I would have gotten an uncorrectable ECC exception. I would have been able to go straight to hardware engineering with that instead of spending many miserable nights debugging an RTOS and ISRs.
