I think, for now, the problem is resolved. There was a debug message on the next line after the timeout that attempted to print out the thread name of the current mutex owner that blocked it. So, the process of events was:

Thread A took the mutex
Thread B asked for the mutex and timed out
Microseconds later and before the log message, Thread A released the mutex
Microseconds later, Thread B attempted to log the error and dereferenced the "owner" pointer that was now set to NULL.

I felt I had removed this and still had the issue but cannot now replicate that so perhaps it was a misbuild or unsaved file.

I'll re-open this thread if it occurs again without the NPD.
