Description

Hi @edenhill,

I'm actually facing some issues regarding timeout with confluent-kafka-go 1.5.2. See below the logs:

Error 1

%4|1614175442.389|SESSTMOUT|rdkafka#consumer-27| [thrd:main]: Consumer group session timed out (in join-state started) after 6000 ms without a successful response from the group coordinator (broker 1, last error was Success): revoking assignment and rejoining group

Also having this

Error 2

%5|1614175531.192|REQTMOUT|rdkafka#consumer-31| [thrd:xxxxxx]: xxxxx/1: Timed out FindCoordinatorRequest in flight (after 60675ms, timeout #0)

Error 3

%5|1614177358.713|REQTMOUT|rdkafka#consumer-31| [thrd:xxxxxxxx]: xxxxx/1: Timed out ApiVersionRequest in flight (after 10010ms, timeout #0)
%4|1614177358.713|REQTMOUT|rdkafka#consumer-31| [thrd:xxxxxxxx]: xxxxxx/1: Timed out 1 in-flight, 0 retry-queued, 0 out-queue, 0 partially-sent requests

They are all related to timeout.

FYI: My microservice is initializing consumers to subscribe to 22 topics, each of them having 6 partitions, which makes one consumer per partition, each of them are belonging to the same group.id.

I'm running this microservice through telepresence.

I saw that there is a similar case mentionned in the confluent-kafka-python repository. https://github.com/confluentinc/confluent-kafka-python/issues/1011#issuecomment-767570642 Could it be related to the 1.6.0 version of librdkafka ?

Thanks in advance :+1:

Checklist

Please provide the following information:

[ ] confluent-kafka-go and librdkafka version (1.5.2)

@edenhill any advice ?

We'll release confluent-kafka-go v1.6.1 shortly, try to reproduce with that version (or current master branch) and if it still an issue reproduce with "debug": "cgrp,broker" to give us an idea what is happening.
