Ranadeep Deb updated KAFKA-10421:
---------------------------------
Description:
I have been experiencing a similar issue in 2.3.0
I have a multi threaded application with each thread sending an individual
message to the broker. There are instances where I have observed that the
Producer threads get stuck on the Producer.send().get() call. I was not sure
what was causing this issue but after landing on this thread
(https://issues.apache.org/jira/browse/KAFKA-8135) I am suspecting that
intermittent network outage might be the reason.
I am curious about how to solve this.

> Kafka Producer deadlocked on get call
> -------------------------------------
>
> Key: KAFKA-10421
> URL: https://issues.apache.org/jira/browse/KAFKA-10421
> Project: Kafka
> Issue Type: Bug
> Components: clients
> Affects Versions: 2.3.0
> Environment: CentOS7
> Reporter: Ranadeep Deb
> Priority: Critical
>
> I have been experiencing a similar issue in 2.3.0
> I have a multi threaded application with each thread sending an individual
> message to the broker. There are instances where I have observed that the
> Producer threads get stuck on the Producer.send().get() call. I was not sure
> what was causing this issue but after landing on this thread
> (https://issues.apache.org/jira/browse/KAFKA-8135) I am suspecting that
> intermittent network outage might be the reason.
> I am curious about how to solve this.
>
> Following are the stack trace of the Java threads
