This can often indicate that you have a situation where you have a test case link to a test case that links back to the parent test case (i.e. an infinite loop).

So if you ever receive this message, check for the following situation:

  • Test Case 1
    • TC1 - Links to Test Case 2
      • TC2 - Links to Test Case 3
        • TC3 - Links back to Test Case 1
