> The {{ListenTCP}} processor maintains an internal queue of events received, 
> which the processor polls during {{onTrigger}} invocation.  This approach 
> allows the framework to control FlowFile creation, but it can also result in 
> large numbers of queued events when the framework does not trigger the 
> processor due to scheduling configuration or resource issues. To provide 
> basic tracking and troubleshooting, implementing debug logging of current 
> queue size and largest queue size at a regular interval would be helpful.
