["Shantanu Deshmukh (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-4493?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16620526#comment-16620526 ] 

Shantanu Deshmukh commented on KAFKA-4493:
------------------------------------------

We are using Kafka 0.10.1.0 and our Kafka producers are consuming huge amount of memory. Heapdump analysis showed almost 1 GB memory consumed by *org.apache.kafka.common.network.Selector* and *org.apache.kafka.common.network.KafkaChannel*.

 

Can I apply this patch for Kafka 0.10.1.0? Sorry, but I don't know much about GIT and patching process. Please guide.

> There have been a few reports of Kafka clients throwing an OOM because they read 4 bytes from the stream and then use that to allocate a ByteBuffer without validating that they are using the right security protocol or even communicating with a Kafka broker.
> It would be good to perform some validation in order to show a useful error message to the user instead of the OOM.
