Nick Travers commented on KAFKA-4669:
-------------------------------------
We hit this again in production, running 0.11.0.1. Same symptoms as previously
reported:

producer-2 Uncaught error in kafka producer I/O thread:

A side-effect was that this effectively caused a deadlock in the affected JVM
as it had a thread waiting for the completion of a send (which awaits on a
latch), but this could never occur as the I/O thread had presumably crashed:

This doesn't look like an easy one to reproduce on our side, so I'm wondering
what the best course of action is here. Is it worth opening this ticket

> KafkaProducer.flush hangs when NetworkClient.handleCompletedReceives throws
> exception

>
> Key: KAFKA-4669
> URL: https://issues.apache.org/jira/browse/KAFKA-4669
> Project: Kafka
> Issue Type: Bug
> Components: clients
> Affects Versions: 0.9.0.1
> Reporter: Cheng Ju
> Assignee: Rajini Sivaram
> Priority: Critical
> Labels: reliability
> Fix For: 0.11.0.1, 1.0.0
>
>
> There is no try catch in NetworkClient.handleCompletedReceives. If an
> exception is thrown after inFlightRequests.completeNext(source), then the
> corresponding RecordBatch's done will never get called, and
> KafkaProducer.flush will hang on this RecordBatch.
> I've checked 0.10 code and think this bug does exist in 0.10 versions.
> A real case. First a correlateId not match exception happens:
> 13 Jan 2017 17:08:24,059 ERROR [kafka-producer-network-thread | producer-21]
> (org.apache.kafka.clients.producer.internals.Sender.run:130) - Uncaught
