Why has my PME7.2.x system CPU usage increased to almost 100%

Issue
Windows Task Manager performance view will  show high CPU usage 90% to 100% being constant over period of time. A further investigation of the running processes will show the WebReach.XMLSubscriptionService.exe*32 using 30% to 50% of CPU usage with high number of Handles and Threads.

Cause
Windows Task Manager performance view will  show high CPU usage 90% to 100% being constant over period of time. A further investigation of the running processes will show the WebReach.XMLSubscriptionService.exe*32 using 30% to 50% of CPU usage with high number of Handles and Threads.
 
Resolution
On system with over 500 devices in the PME7.2.2 system the root cause of this constant high CPU usage was traced back to a process configured to pull real time data to third party system. This process involved XML scraping of the Diagram Web pages. Once this process was terminated the CPU usage went back to normal.
