Date Fri, 22 Sep 2017 12:25:00 GMT
Mudit Garg created KAFKA-5963:

             Summary: Null Pointer Exception on server
                 Key: KAFKA-5963
                 URL: https://issues.apache.org/jira/browse/KAFKA-5963
             Project: Kafka
          Issue Type: Bug
            Reporter: Mudit Garg

I am using Kafka I am sending the logs to Kafka Streams. 
Initially, everything works fine but after some time when the server is idle and no logs are
produced, we get *Null Pointer Exception on the server* and *nothing gets pushed into Kafka*.
Following is the stack trace :
	at org.apache.kafka.common.network.Selector.poll(Selector.java:187)
	at org.apache.kafka.clients.producer.internals.Sender.run(Sender.java:154)
	at org.apache.kafka.clients.producer.internals.Sender.run(Sender.java:101)
	at java.lang.Thread.run(Thread.java:745)

I checked the code at https://github.com/apache/kafka/blob/

Looks like transmissions object is null.
