I've a 2960S in a stack, it's showing high CPU sometimes, but I can't identify what is the process responsible for that. I research and I could see that EEM script is not available on the 2960S in order to find the process.
Anyone has some idea how can I identify the high CPU on the device ?

The problem happen before, so we decided to upgrade the code but the problem was not solved.

If @Mark Malone suggestion doesn't reveal any culprits you may be looking at a case of processed-switched packets. The fact that a IOS upgrade didn't fix the problem makes me think it is not a bug but a symptom of the type of network traffic being processed through the switch.
What is the output of: show controllers cpu-interface
cheers,
