I have an odd problem. I set the Back Pressure Object threshold on a link between two Processors to 1, but 200 flowfiles are passed to the queue before back pressure is honored. I need the back pressure to be set to a small number of flowfiles to keep the source from flooding the destination. Has anyone come across this problem before? I am running 12 instances of NiFi on version 1.1.1 on Ubuntu 14.04.
