The CPU Utilization (Processor\% Processor Time) for the system processor has exceeded the threshold. Once exceeded overall system performance may diminish significantly which will result in poor operating system and application performance.
When a computer is under substantial load for a sustained period of time it can be caused by any of the following conditions:
The resource requirements for the application set installed on the computer exceeds the capabilities of the computer’s hardware configuration.
Demand on the computer resources has increased over time and the computer hardware configuration is no longer able to satisfy increasing demand.
An application that is running on the computer may have entered into an unhealthy state and is now demanding irregular volumes of system resources.

To resolve this issue an administrator can perform the following tasks:
1. Evaluate the % Processor Utilization counter for each of the processes running on the server. This can be done by using either Task Manager or the Performance Monitoring snap-in. Determine which process(s) are consuming the most resources and monitor them over time to determine whether they appear to be returning to normal performance ranges. If not, addition application specific diagnostics should be performed to determine the most appropriate way to resolve the issue.
2. If it is determined that client load has increased over time and the computer is simply no longer able to satisfy demand, perform additional performance monitoring procedures to determine if basic hardware upgrades can enable the computer to return to optimal performance ranges.
3. If it has been determined that the application has entered into an unhealthy state, possibly due to a product defect, it might be necessary to restart the application. If the issue persists, you might need to contact the application vendor.
