When we run tests via Jenkins we see that the build is still running long after the scenario ends. When we log into the LoadRunner Controller/Jenkins Slave we see that there is a window open indicating that The HP LoadRunner Controller has stopped working. In order for the Jenkins build to completely stop I have to kill that window (WerFault.exe) Jenkins's reports:

Error: The Controller is still running...

Error: Test FAILED. 1 errors occured during scenario execution.
Error: Cannot close Controller gracefully, exception details:
