Looks like all the utilization is interrupt-based. Meaning that packets
are punting to the RP for some reason. There are various 'show mls'
commands that will give you a clue why. What does the config look like?
Keep in mind that there are many caveats on the 6500s that can cause
packets to punt to the RP, and make the performance drop like a rock.

Hi Group,
I was wondering if anyone had any good troubleshooting tips on the 6513
running IOS - in regards to troubleshooting high CPU utilisation.
I have an issue on one of our core switches where it is averaging 30% -
50%
util - but no record of which process is using it.
WANCORE1#sh processes cpu sorted
CPU utilization for five seconds: 35%/31%; one minute: 37%; five
