Wouter Bancken commented on KAFKA-6817:
---------------------------------------

Is there any news on a solution/workaround for clients not using Kafka Streams?

We have tried setting transactional.id.expiration.ms to its maximum value (24 
days) as mentioned earlier in the comments and this greatly reduces the number 
of occurrences but it does not eliminate the error. 

In our use cases it is possible that a producer will remain active for a long 
period without writing to a certain topic.

> We have reproduced the error with a smaller example application. The error 
> occurs after 10 minutes of producing messages that have old timestamps (type 
> 1 year old). The topic we are writing to has a retention.ms set to 1 year so 
> we are expecting the messages to stay there.
> After digging through the ProducerStateManager-code in the Kafka source code 
> we have a theory of what might be wrong.
> The ProducerStateManager.removeExpiredProducers() seems to remove producers 
> from memory erroneously when processing records which are older than the 
> maxProducerIdExpirationMs (coming from the `transactional.id.expiration.ms` 
> configuration), which is set by default to 7 days.
