Hello NiFi Community!   I have a three-node NiFi cluster. I use this to ingest data from multiple source systems. From time to time, we experience this issue where the flowfiles are getting stucked in round robin queues and just sit idly there.      I've also tried adding funnels just to test if they can still proceed downstream.   Upon monitoring the disk usage of the cluster, it never exceeds 30% utilization.   Anyone knows what's causing this issue? Tried checking the nifi-app logs but no luck.   Thank you!     ... View more
