Hi Joe, Been using NiFi for a while and I have always been wondering why I was capping at 10 thread. Now I have my answer :) It would be great to have a visual cue (warning sign) next to Active thread on the left hand side, in case the max number is reached too often. Giving the user an idea of how many threads are available to him to as a helper would be great.
