I'm experiencing an error with a particular stream, which is consistently giving the following error at start-up time :
``` 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 ``` 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. 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 but is otherwise stock 2.3.0. I don't see any errors or unusual messages on the broker side. I created issue https://issues.apache.org/jira/browse/KAFKA-8803 but basically I'm stuck with a non-starting stream. Any ideas?
