"The processor runs two processes, Cat4k Mgmt HiPri and Cat4k Mgmt 
LoPri. These two processes share total CPU usage among other IOS 
processes. The reason there are two processes is when a job on the Cat4k 
platform takes longer than expected or exceeds the maximum allocated CPU 
time, the job is run under Low-Priority for a period of time until its 
usage is reduced, giving other (Cisco IOS) processes a chance to run."
