This doesn't look like a deadlock (or you would see the thread locked on a thread-waiting operation). Maybe it's a livelock, or maybe simply a very long-running process, or an infinite loop.

You'd find more about it by doing more snapshots, and finding what the common top part of the traceback is. It will point you to the part of the code that's repeatedly called.

Could anybody explain what's wrong here and how to repair it?

Stays the part above (maybe partially) accross several
"DeadlockDebugger" invocations (or changes the tail of your
traceback continously)?

In this case, there would seem to be some infinite loop caused
by the AT "ReferenceEngine" (I like it).

As you supposed the tail changes if I invoke DeadlockDebugger several times.
Here are 3 more examples besides the one I sent before:
