Occasionally log stash Kafka consumer produces
[INFO ][org.apache.kafka.clients.FetchSessionHandler] [Consumer clientId=elk-logstash-indexer-69bb94c58-4x7q8-4, groupId=containers] Node 1 was unable to process the fetch request with (sessionId=1684033008, epoch=560340): INVALID_FETCH_SESSION_EPOCH.
and stops consuming logs from kafka topics. The same question occurs in other setups but there is no clear guidance where to look for details or how to solve it. For now only restarting of the logstash help but that is not the resolution. Is there a clue what is wrong and why that happens?
