hello. I'm having a problem with Nifi, so I'm posting a question. In my Nifi, an error occurs in one node, and there is a problem that the node is disconnected in the cluster A total of 6 nodes were configured as a cluster with 3 nodes in different datacenters. The current configuration is collecting network logs through ListenSyslog, ParseCEF, and then sending them to graylog.   It receives an average of 721MB per 5 minutes, but there is a problem that the cluster becomes Disconnected with a Queue Full error occurring on some nodes. The error message is below.     Communication Failed with Remote Address[null]: java.lang.illegalStateException: Queue full     It says Queue full, but I don't know what kind of queue the error message points to and how to solve it. My nifi.properties configuration are below.     nifi.administrative.yield.duration=30 sec # If a component has no work to do (is "bored"), how long should we wait before checking again for work? nifi.bored.yield.duration=10 millis nifi.queue.backpressure.count=800000 nifi.queue.backpressure.size=10 GB # FlowFile Repository nifi.flowfile.repository.implementation=org.apache.nifi.controller.repository.WriteAheadFlowFileRepository nifi.flowfile.repository.wal.implementation=org.apache.nifi.wali.SequentialAccessWriteAheadLog nifi.queue.swap.threshold=100000 nifi.provenance.repository.index.shard.size=8 GB # Indicates the maximum length that a FlowFile attribute can be when retrieving a Provenance Event from # the repository. If the length of any attribute exceeds this value, it will be truncated when the event is retrieved. nifi.provenance.repository.max.attribute.length=65536 nifi.provenance.repository.concurrent.merge.threads=2 # Volatile Provenance Respository Properties nifi.provenance.repository.buffer.size=100000 # Volatile Status History Repository Properties nifi.components.status.repository.buffer.size=1440 nifi.components.status.snapshot.frequency=1 min         The servers have specifications of 48 cores (HyperThread enable) and 256GB Memory. please help me thank you.😭 ...
