GitHub user codelipenghui added a comment to the discussion: Failed messages 1 with no more exception message

@Aaronzk There is an internal pending queue with 1000 messages by default for a producer. if the server-side with a slow response but the application send messages very fast that will fill up the pending queue, so by default, you will get the above exception, it's a fail-fast strategy. 

Another available strategy is to block the caller thread if the pending queue filled up, you can add `.blockIfQueueFull(true)` when creating the producer.
