Dano, That number indicates the number of Terminated Threads. I.e., the threads that were left behind when you hit Terminate. They will go away on restart, or if the threads ever actually complete. For example, if the thread was busy doing something that takes an hour, and you terminate it, it may finish up after an hour and go away. But if it's in a blocking call that never returns, then you'll have to restart NiFi in order for that thread to ever die.

See attached screen shot. Also in on the processor that we killed, we see that an indicator in red with the (1). What do these mean and how/when do these get cleaned up/cleared? Do we need to restart the nodes in the cluster to clear this up? Regards, Dano <Screen Shot 2019-07-25 at 9.20.29 PM.png><Screen Shot 2019-07-25 at 9.15.02 PM.png>
