I see verfy high cpu utilization on my 4507 switch
The sh proc cpu shows the catmgmt -lo priority process with high utilization
the show platform health shows high utilization for the KxAclPathMan create/ process
after reading the troubleshooting guide it points to see whether there are any interface flaps but i do not see any
Any inputs will help
IOS - 12.1 20 EW2
Have you enabled looging even link-status under your interfaces?
4500 does not show any interface flaps if the above command has been configured
