That's what I thought. So now you see the problem: the extract I provided was the complete lifecycle of that instance, and there is nothing in the log to indicate "why" the termination happened. Either the log levels in all the callers need to be matched (which is itself sucky for both modularity and readability) or they should provide information along the lines I indicated so the single terminate message has the needed info.
