Kindly post the complete output to the command "sh proc cpu sort | ex 0.00".

Hi , 

These two processes seem to be the culprits : 

56 153874756 680837438 226 2.61% 2.65% 2.69% 0 Cat4k Mgmt HiPri
57 363174821047547247 34 95.64% 95.42% 95.32% 0 Cat4k Mgmt LoPri

We would need the output of "sh plat health" 

This seems to be a fairly common issue as documented by CISCO here  : 

This is documented here : http://www.cisco.com/c/en/us/support/docs/switches/catalyst-4000-series-switches/65591-cat4500-high-cpu.html

Several entries are available on supportforums for this issue. 

https://supportforums.cisco.com/discussion/11730586/high-cpu-utilization-cisco-ios-catalyst-4500

P.S. Don't forget to mark the correct answers !

Ok already upload the output sh plat health, thanks
