We have set a Timeout of 10 mins.

If the script is frozen or UFT is not reacting the call: QTPApplication.Test.Stop will never finish.

The plugin in this case,  is  unable to stop the Execution and wait there ... well for a long time.

If I kill the UFT process manually I get this ( StackTraceIn my case it means that UFT was stuck there for more than a minute)

My proposal is to start a totally separate process that will act like a timebomb. After a specific Timeout it simply kills UFT. This process should be stopped if the Test Case is finished and for each test Execution rescheduled.
