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=


?

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!
