to be honest it is very very rare for me to see the trouble originating from the switch, it is almost always something out towards the customer. Especially if you try to roll this to a new SM and the trouble follows. I have had similier troubles in the past, for every errored second I had, I had an identical slip, looked like a timing issue.It would often turn out to be a defective t3 card. switch it over to protect and all cleared..
