Mail delays are experienced when BlackBerry Enterprise Service experiences high CPU utilization with configuration database connection issues

• BlackBerry® Enterprise Server 5.0 SP3 for Microsoft® Exchange
  

While the BlackBerry® Enterprise Server is undergoing high CPU usage with reported mail delays the BlackBerry services logs will indicate database connection failures. The line below will be displayed in the BlackBerry Alert Services (ALRT) logs when high CPU utilization issue first starts:

After this first indication, the logs may mainly log the following line:
