Raman Gupta commented on KAFKA-8803:
------------------------------------
[~bchen225242] IIRC, it seems to happen randomly to specific streams upon
application startup. Once it happens, the stream usually does not recover on
its own unless the brokers are restarted, even after restarting the application.
I doubt the issue is broker overload. Note also that most of the streams in my
system are totally fine -- when the issue (seemingly) randomly happens, it
happens only to specific streams. If it was a broker overload issue, I would
expect more streams to be affected right? Plus these brokers are really not
doing that much.
That being said I can still provide the info. When you say "request metrics"
what metrics are you referring to? The producer metrics?
Right now I don't have any streams with this issue, but I can make a note to
check specific things the next time it happens.

> 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.
