I opened a TAC case on it. It's a bug that has been seen before. They don't have exact cause. TAC requested me to run a debug image and gather data, etc, etc, etc....
Honestly, I don't have time for that. Given what we pay for Cisco products, they need to reproduce it and fix it themselves. The bug is related to an ARP storm. I gave them my network layout (Visio). They should be able to recreate and generate an ARP storm. If they can't, Cisco is in big trouble as a company (more so than I thought).
