Ted Yu commented on KAFKA-6544:
-------------------------------
One option is to shutdown the process in SocketServer :
{code}
case e: ControlThrowable => throw e
case e: Throwable => error("Error occurred", e)
{code}
upon seeing IOException with the proper message.
> kafka process should exit when it encounters "java.io.IOException: Too many
> open files"

> Key: KAFKA-6544
> URL: https://issues.apache.org/jira/browse/KAFKA-6544
> Project: Kafka
> Issue Type: Bug
> Components: admin, network
> Affects Versions: 0.10.2.1
> Reporter: Yu Yang
> Priority: Major
>
> Our kafka cluster encountered a few disk/xfs failures in the cloud vm
> instances. When a disk/xfs failure happens, kafka process did not exit
> gracefully. Instead, it run into "<defunct>" status, with port 9092 still be
> reachable. when failures like this happens, kafka should shutdown all
> threads and exit. The following is the kafka logs when the failure happens:
> {code:java}
