> We are regularly seeing OOME errors on a kafka producer, we first saw :

> Usually the app runs fine within 200/400 MB heap and a 64 MB Metaspace. And
> we are producing small messages 500B at most.
> Also the error don't appear on the devlopment environment, in order to
> identify the issue we tweaked the code to give us actual data of the
> allocation size, we got this stack :

> Notice the size to allocate {{1213486160}} ~1.2 GB. I'm not yet sure how this
> size is initialised.
> Notice as well that every time this OOME appear the {{NetworkReceive}}
> constructor at
> https://github.com/apache/kafka/blob/0.9.0.1/clients/src/main/java/org/apache/kafka/common/network/NetworkReceive.java#L49
> receive the parameters : {{maxSize=-1}}, {{source="-1"}}
> We may have missed configuration in our setup but kafka clients shouldn't
> raise an OOME. For reference the producer is initialised with :
> {code}
> Properties props = new Properties();
> props.put(BOOTSTRAP_SERVERS_CONFIG, properties.bootstrapServers);
> props.put(ACKS_CONFIG, "ONE");
> props.put(RETRIES_CONFIG, 0);
> props.put(BATCH_SIZE_CONFIG, 16384);
> props.put(LINGER_MS_CONFIG, 0);
> props.put(BUFFER_MEMORY_CONFIG, 33554432);
> props.put(REQUEST_TIMEOUT_MS_CONFIG, 1000);
> props.put(MAX_BLOCK_MS_CONFIG, 1000);
> props.put(KEY_SERIALIZER_CLASS_CONFIG,
> StringSerializer.class.getName());
> props.put(VALUE_SERIALIZER_CLASS_CONFIG,
> JSONSerializer.class.getName());
> {code}
> For reference while googling for the issue we found a similar stack trace
> with the new consumer API on the same class on the ATLAS project:
> https://issues.apache.org/jira/browse/ATLAS-665
> If anything is missing please reach out.
