That's a bug the HULC process getting so high , just put in Google 2960x HULC bug , this process effects multiple platforms and its on most releases as well , from other link and other poster Leo has put this version as one that may not be effected by HULC 15.0(1)SE3 , it can reach up to 30% of cpu sometimes
163 2331774448 291273722 8005 16.56% 15.85% 15.75% 0 Hulc LED Process
When you see it at 90% is this bug at the top if the list as well , the only way to fix this is to get on an IOS that's not effected by it , check as well what the interrupt is at this time and whats happening on the switch in terms of the amount of traffic being pushed through , these are user access switches so should not have like servers connected to them or you will see interrupt get high quick
Whats more concerning is the interrupt amount 26% that means your over utilizing the switch its taking more traffic than it can handle , interrupt should not go over 4%
If ports are not in use shut them down as that can bring the cpu down for HULC too and I would change the image but one thing I have noticed with this bug it usually does not effect the actual switch performance
Most 2960s cant do cef so everything will be process switched in hardware anyway but that's not going to help the cpu having a high load
