> We are seeing the following exception in our Kafka application:

> ERROR o.a.k.s.p.internals.StreamTask - task [0_0] Failed to close producer due to the following error: org.apache.kafka.streams.errors.StreamsException: task [0_0] Abort sending since an error caught with a previous record (key 222222 value some-value timestamp 1519200902670) to topic exactly-once-test-topic- v2 due to This exception is raised by the broker if it could not locate the producer metadata associated with the producerId in question. This could happen if, for instance, the producer's records were deleted because their retention time had elapsed. Once the last records of the producerId are removed, the producer's metadata is removed from the broker, and future appends by the producer will return this exception. at org.apache.kafka.streams.processor.internals.RecordCollectorImpl.recordSendError(RecordCollectorImpl.java:125) at org.apache.kafka.streams.processor.internals.RecordCollectorImpl.access$500(RecordCollectorImpl.java:48) at org.apache.kafka.streams.processor.internals.RecordCollectorImpl$1.onCompletion(RecordCollectorImpl.java:180) at org.apache.kafka.clients.producer.KafkaProducer$InterceptorCallback.onCompletion(KafkaProducer.java:1199) at org.apache.kafka.clients.producer.internals.ProducerBatch.completeFutureAndFireCallbacks(ProducerBatch.java:204) at org.apache.kafka.clients.producer.internals.ProducerBatch.done(ProducerBatch.java:187) at org.apache.kafka.clients.producer.internals.Sender.failBatch(Sender.java:627) at org.apache.kafka.clients.producer.internals.Sender.failBatch(Sender.java:596) at org.apache.kafka.clients.producer.internals.Sender.completeBatch(Sender.java:557) at org.apache.kafka.clients.producer.internals.Sender.handleProduceResponse(Sender.java:481) at org.apache.kafka.clients.producer.internals.Sender.access$100(Sender.java:74) at org.apache.kafka.clients.producer.internals.Sender$1.onComplete(Sender.java:692) at org.apache.kafka.clients.ClientResponse.onComplete(ClientResponse.java:101) at org.apache.kafka.clients.NetworkClient.completeResponses(NetworkClient.java:482) at org.apache.kafka.clients.NetworkClient.poll(NetworkClient.java:474) at org.apache.kafka.clients.producer.internals.Sender.run(Sender.java:239) at org.apache.kafka.clients.producer.internals.Sender.run(Sender.java:163) at java.lang.Thread.run(Thread.java:748) Caused by: org.apache.kafka.common.errors.UnknownProducerIdException
> {code}
> We discovered this error when we had the need to reprocess old messages. See more details on [Stackoverflow|https://stackoverflow.com/questions/49872827/unknownproduceridexception-in-kafka-streams-when-enabling-exactly-once?noredirect=1#comment86901917_49872827]
> 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.
