Hi Zach
there is a rumour that today thursday is a holiday? in server.properties how are you configuring your server? specifically what are these attributes? num.network.threads= num.io.threads= socket.send.buffer.bytes= socket.receive.buffer.bytes= socket.request.max.bytes= num.partitions= num.recovery.threads.per.data.dir= ?

This is very disconcerting! ________________________________ From: Zac Harvey <zac.har...@welltok.com> Sent: Wednesday, November 23, 2016 5:07:45 AM To: users@kafka.apache.org Subject: Messages intermittently get lost I am playing around with Kafka and have a simple setup: * 1-node Kafka (Ubuntu) server * 3-node ZK cluster (each on their own Ubuntu server) I have a consumer written in Scala and am using the kafka-console-producer (v0.10) that ships with the distribution. I'd say about 20% of the messages I send via the producer never get consumed by the Scala process (which is running continuously). No errors on either side (producer or consumer): the producer sends, and, nothing... Any ideas as to what might be going on here, or how I could start troubleshooting? Thanks!
