Knowledge Base documents like this: 3rd party application, CAD-DUCT, is crashing and 3rd party application, CADWorx, is crashing are a bit short of information I think or is there really a message in AutoCAD that specifies that the crash is in a 3rd party application?
Here is from one of the KB documents:
