> If a Processor has multiple threads and only a single FlowFIle, Thread 1 will
> process the FlowFile while Thread 2 is continually triggered to run. As a
> result, the number of tasks completed runs up into the 100's of thousands or
> millions in a five-minute window sometimes, without any real work being done.
