[jira] [Commented] (KAFKA-682) java.lang.OutOfMemoryError: Java heap space

    [ https://issues.apache.org/jira/browse/KAFKA-682?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13544119#comment-13544119 ]

Joel Koshy commented on KAFKA-682:
----------------------------------

You might need to increase your heap size. What do you have it set to right now? Would you be able to run the broker with -XX:+HeapDumpOnOutOfMemoryError to get a heap-dump?

In case you are overriding defaults - what's the replication factor for the topic, num-required-acks for the producer requests, and producer request timeout? Are any requests going through or are the produce requests expiring?
