Hi gang, I have started receiving this error after perhaps 24 hours of run time. The first queue in our flow has a very large backlog by the time this error arrives. What is odd is that the incoming message rate is fairly constant at all times and while I am watching NiFi during the day, we never have any backlogs. So this leads me to believe that the backlog is a symptom of NiFi slowing itself down, not the cause of the problem. I am using 4 threads per processor for our main flow to handle the throughput.
Any ideas what causes this to happen and how I can fix it? TIA, Phil
