Offset commit failed when appending to log due to org.apache.kafka.common.errors.TimeoutException

[Roman Nikolaevich]

Hi folks,

We have recently got a strange issue with kafka consumer.
Consumer thread was hanging infinitely.

Can someone advise how to approach this?
kafka version is 1.0.2.

we have found following error at broker side.
[2020-01-14 12:17:54,454] DEBUG [GroupMetadataManager brokerId=1002] Offset

here is also tread dump on consumer side
