    An inconsistency with the eXtreme data format (XDF) metadata can
    lead to a hang in certain scenarios where a class definition
    contains the same field name multiple times within the type
    hierarchy.  A hang might occur, depending on the order in which
    the fields of the class are processed.
    

Problem conclusion

  • A fix was provided to prevent the hang in this situation.
