---------------------------------
Attachment: server.log.2015-09-23-09.gz
Server logs for the day which appears to have caused the processor thread to die
> Processor thread dies due to an uncaught NoSuchElementException
> ---------------------------------------------------------------
>
> Key: KAFKA-2595
> URL: https://issues.apache.org/jira/browse/KAFKA-2595
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 0.8.2.0
> Reporter: Shaun Senecal
> Attachments: server.log.2015-09-23-09.gz
>
>
> We are getting uncaught exceptions which seem to kill the processor threads.
> The end result is that we end up with a bunch of connections in CLOSE_WAIT
> and eventually the broker is unable to respond or hits the max open files
> ulimit.

> The issue appears to be the same as KAFKA-1577, except that its not happening
> during shutdown. We haven't been able to isolate when this happens, so we
> dont have a good way to reproduce the issue.
> It also looks like KAFKA-2353 would work around the issue if it could be
> back-ported, but the root cause should probably be fixed as well.
