Symptoms

Assume that you try to run a Web test in Microsoft Visual Studio 2010 or in Microsoft Test Manager 2010. However, the test controller (Qtcontroller.exe) crashes with an OutOfMemoryException exception or an unhandled exception if the test result file is large. Specifically, this issue occurs when the test results (.webtestresults) file is 1.5 gigabytes (GB) or larger.

Note Additionally, when the test controller crashes with an unhandled exception, you receive the following error message:
(QTController.exe, PID <n>, Thread <n>) TcmRunner: Unhandled exception for run [90]: Internal Error!
Failed to acquire a ReaderLock

Cause

This issue occurs because the Web test runs multiple iterations, and then produces a large result file. This behavior may consume a large amount of memory. However, Qtcontroller.exe is a 32-bit process. 

Note The memory space of 32-bit processes is limited to 2 GB.

Resolution

After you apply the hotfix, Qtcontroller.exe runs as a 64-bit process in x64-based operating systems.
