This is caused by calling Tibco's Environment.Open() without calling a matching Tibco Environment.Close(). Until the reference count reaches 0, Tibco is not actually disposed of properly.

To fix this issue in C#, ensure that there is a .Dispose() method on every single class that calls Tibco's Environment.Open(), and this .Dispose() call calls Tibco's Environment.Close().
