> If i have an RPG sending to a input port on another NiFi and that input port is no longer accepting files because of backpressure on the input port connection, the sending NiFi starts logging that the destination port is full.
> The potential problem is that it create a log message for every file that is queueing up on the connection(s) feeding that RPG destination input port.  This logging seems excess.
>  
> The critical issue:
> Also when i select "disable transmission" I get the spinning wheel but thread does not complete. Entire instance is now unresponsive.
> Even though it became hung on request to disable transmission, on restart it started running again. Hung again. 
> The only options for regaining control is to either restart with auto resume state set to false or take back pressure off destination input port so thread can complete.
