Consider the following scenario:
- An application or service runs in Windows Server 2008, Windows Vista, Windows XP Service Pack 3 (SP3) or another system that has Microsoft XML Core Services (MSXML) 6.0 installed.
- The application or service uses MSXML 6.0 to handle XML requests.
In heavy stress situations, the CPU usage of an application or service reaches 100%. If this problem occurs on a uniprocessor computer, the whole system crashes. If this problem occurs on a multiprocessor computer, the whole system encounters high CPU usage. In Task Manager, you may see that the CPU usage of one processor is 100%.
For example, the MonitoringHost.exe process in the System Center Operations Manager 2007 encounters high CPU usage because of this problem.
