This weekend our data center switch had a meltdown. I consoled into the switch and noticed CPU utilization was at 100%. I did "show proc cpu sort" and arp input was at 14%. I could not isolate what other process hogged the CPU so I rebooted the switch and it solved the issue. I also did a bug tool search on this particular IOS and nothing really stands out. We have this IOS for almost 1 year and half.
I am wondering if there is an IOS command that can backtrace what process hogged the CPU and found the root cause of the problem.
