Tom,

I concur with Hoff, Hein, and Brian: The LINK map and the compiled code machine language listing can help. HOWEVER (capitalization for emphasis), it is highly likely that the image is "hung" in some library routine or other unrelated to the actual problem.

Tracing the stack can yield a solution, and there are also other possibilities (e.g., some routine disabled AST dispatching, and the process is waiting for an AST to be processed).

The best answer is to get a process dump, and analyze what is the precise state of the process. "Hung" is a symptom, not a process state or diagnosis.
