> Hi Kafka Dev Team,
> When I run the test to send message to single partition for 3 minutes or so
> on, I have encounter deadlock (please see the screen attached) and thread
> contention from YourKit profiling.
> Use Case:
> 1) Aggregating messages into same partition for metric counting.
> 2) Replicate Old Producer behavior for sticking to partition for 3 minutes.
> Here is output:
> Frozen threads found (potential deadlock)
>
> It seems that the following threads have not changed their stack for more
> than 10 seconds.
> These threads are possibly (but not necessarily!) in a deadlock or hung.
