> One streams app is consistently failing at startup with the following 
> exception:
> {code}
> 2019-08-14 17:02:29,568 ERROR --- [2ce1b-StreamThread-2] 
> org.apa.kaf.str.pro.int.StreamTask                : task [0_36] Timeout 
> exception caught when initializing transactions for task 0_36. This might 
> happen if the broker is slow to respond, if the network connection to the 
> broker was interrupted, or if similar circumstances arise. You can increase 
> producer parameter `max.block.ms` to increase this timeout.
> org.apache.kafka.common.errors.TimeoutException: Timeout expired after 
> 60000milliseconds while awaiting InitProducerId
> {code}
> These same brokers are used by many other streams without any issue, 
> including some in the very same processes for the stream which consistently 
> throws this exception.
> *UPDATE 08/16:*
> The very first instance of this error is August 13th 2019, 17:03:36.754 and 
> it happened for 4 different streams. For 3 of these streams, the error only 
> happened once, and then the stream recovered. For the 4th stream, the error 
> has continued to happen, and continues to happen now.
> I looked up the broker logs for this time, and see that at August 13th 2019, 
> 16:47:43, two of four brokers started reporting messages like this, for 
> multiple partitions:
> [2019-08-13 20:47:43,658] INFO [ReplicaFetcher replicaId=3, leaderId=1, 
> fetcherId=0] Retrying leaderEpoch request for partition xxx-1 as the leader 
> reported an error: UNKNOWN_LEADER_EPOCH (kafka.server.ReplicaFetcherThread)
> The UNKNOWN_LEADER_EPOCH messages continued for some time, and then stopped, 
> here is a view of the count of these messages over time:
>  !screenshot-1.png! 
> However, as noted, the stream task timeout error continues to happen.
> I use the static consumer group protocol with Kafka 2.3.0 clients and 2.3.0 
> broker. The broker has a patch for KAFKA-8773.
