Hi, First, thanks alot for a great product! :)
My issue is this. Create a PG, inside it create an out-port and connect it to another out-port outside the PG. Start the out-port inside the PG. My CPU load then sky-rockets (from ~5-10% to 200-300% on my laptop to 500-1000% on my servers) :/ If I however connect a processor, running or not (e.g the FlowFile Generator) to the out-port inside the PG, CPU load returns to "normal". Also if I just stop the running out-port inside the PG, with nothing connected on the input side, all is normal. Have not gotten around to looking at the thread-dump yet. Ive tested this both on clustered and a clean standalone version of NiFi 1.7.1 (Inside docker contianer that is, but as far as I can tell, this does not matter). Im on CentOS7.4 with Java 1.8_144. Can anyone recreate this? Cheers, KT :)
