I have a problem in my workflow where the workflow ends when its running in a slow environment.

Its a state machine workflow using xoml files.

My problem is the following:

The client has been facing problems were the workflow ends prematurely. This occurs at random times.

After looking into this I found that everytime I debug the application and step through the code the overriden method Cancel of Activity class is entered, hence the workflow ends.

When I run the application normally it works fine. So my thinking is when the workflow is ran under a slow environment it somehow enters the Cancel method.

Further, I added some Thread.Sleep snippets in the code and ran the app. Again the workflow ends when it shouldn’t.

So my thinking is when the workflow is ran under a slow environment it somehow enters the Cancel method. Why this happens I do not know.

The code was taken from the following sample http://www.microsoft.com/downloads/details.aspx?FamilyId=A438A9B9-9F15-42EC-866F-2EA58E10DB36&displaylang=en

Does anyone know why it ends? or how I can find out why the Cancel method is entered?
