SYMPTOMS
When you run a unit test application, Microsoft Visual Studio 2005 may stop responding. Or, when you build a unit test application, Visual Studio 2005 may use 85 percent or more of the CPU resources.

Note This problem does not occur if you run the unit test application by using the Mstest.exe application.



CAUSE
This problem occurs because the file updates are recursively checked in to the source control.
