> Testing ListenSMTP processor. It has some bad behavior whereby it will not
> stop when told to. But on the UI i cannot tell that at all. So, i went to
> edit the processor config which I was able to do. Then went to start it and
> I get

> 7667f0c7-0156-1000-8181-5b556f8544da cannot be started because it is not
> stopped. Current state is STOPPING
> {quote}
> There should be a visual indicator of its status and we should not be able to
> edit a processor which is not stopped.
> More details on that specific case here

> But key is that a bad behaving processor can allow the user to do things they
> should not be able to.
