I am trying to do channel.basicReject() to requeue message based on some condition by creating an MethodInterceptor ConsumerAdvice and adding it to SMLC factor.setAdviceChain(new ConsumerAdvice()). I also have concurrentConsumer configuration which is set to 10. The moment my reject condition is met I issue basicReject command and it gets redelivered and processed by another consumer. During this redelivery process I get the below error,
2019-11-07 17:34:13.268 ERROR 29385 --- [ 127.0.0.1:5672] o.s.a.r.c.CachingConnectionFactory : Channel shutdown: channel error; protocol method: #method<channel.close>(reply-code=406, reply-text=PRECONDITION_FAILED - unknown delivery tag 1, class-id=60, method-id=80)

My message is not getting lost but I am seeing a bunch of above errors and unable to understand why this is happening. If anyone has any clues please guide me.

You need to show your code and configuration.
It seems like the SMLC has its default configuration to automatically acknowledge messages and this failure is because you already rejected it; why are you interacting with the channel directly?
You can simply throw an exception and the container will reject the message on your behalf.
I don't know if it will helpful for someone.
I had the same error because of invalid input data. But when I added next properties:
"rabbit.listener.acknowledgeMode": "MANUAL",
"rabbit.listener.defaultRequeueRejected": "true",
"rabbit.listener.prefetchCount": "1",
the problem stop to break my program but only had stopping my listener

I am trying to create a bare-bones skeleton integration test for Kafka with TestContainers: just publish message to topic and check it arrives to it (entire setup below).

),

// Act
producer.send(ProducerRecord("topic", "Hello there!"))
producer.flush()

Test passes (ProducerTests > do nothing special() PASSED) however log is flooded with producer and consumer warnings. Is this expected? Am I missing some configuration for broker/leader to make this errors go away?

Update: I removed Spring dependencies completely however the problem persists and that suggests I am misconfiguring TestContainers.
I'm using pika in a kubernetes cluster and consuming messages from a queue, which triggers initiating a function in a new thread. However RabbitMQ seems crash, these are the best logs I've found so far:

Is there anything inherently wrong with my implementation and strategy for handling messages and workloads in separate threads that is causing this to happen?
Pika isn't thread safe by default. You should ideally keep one connection per thread.
There are a bunch of example implementation here, and I have a thread safe rpc example here that you look at as well, but I would recommend using one of their reference implementations for threading.
I'm using a SimpleMessageListenerContainer as a basis for remoting over AMQP. Everything goes smooth provided that the RabbitMQ broker can be reached at process startup. However, if by any reason it can't be reached (network down, permissions problem, etc...) the container just keeps retrying to connect forever. How can I set up a retry behaviour in this case (for example, try at most 5 times with an exponential backoff and then abort, killing the process)? I've had a look at this, but it doesn't seem to work for me on container startup. Can anyone please shed some light?
At the very least, I'd like to be able to catch the exception and provide a log message, instead of printing the exception itself as is the default behaviour.
How can I set up a retry behaviour in this case
There is no sophisticated connection retry, just a simple recoveryInterval. The assumption is that the broker unavailability is temporary. Fatal errors (such as bad credentials) stop the container.
You could use some external process to try connectionFactory.createConnection() and stop() the SimpleMessageListenerContainer when you deem it's time to give up.
You could also subclass CachingConnectionFactory, override createBareConnection catch the exception and increment the recoveryInterval, then call stop() when you want.
EDIT
Since 1.5, you can now configure a backOff. Here's an example using Spring Boot...
#SpringBootApplication
public class RabbitBackOffApplication {
public static void main(String[] args) {
SpringApplication.run(RabbitBackOffApplication.class, args);
}
#Bean(name = "rabbitListenerContainerFactory")
public SimpleRabbitListenerContainerFactory simpleRabbitListenerContainerFactory(
SimpleRabbitListenerContainerFactoryConfigurer configurer,
ConnectionFactory connectionFactory) {
SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();
configurer.configure(factory, connectionFactory);
BackOff recoveryBackOff = new FixedBackOff(5000, 3);
factory.setRecoveryBackOff(recoveryBackOff);
return factory;
}
#RabbitListener(queues = "foo")
public void listen(String in) {
}
}
and

This seems to have been fixed by moving to Mule 3.4 CE x64. However, what went wrong with 3.3.1 CE is unknown.
I'm trying to implement error handling logic in my Mule flow and I want to test for HTTP status codes. I've implemented a Message filter, and want my catch-exception-strategy to catch the org.mule.api.routing.filter.FilterUnacceptedException the message-property-filter throws, which I can do, but I want it to be almost nested, but I know I can't do that, so I'm combining my logic statement by an AND operation, like so:
<catch-exception-strategy when="#[exception.causedBy(org.mule.api.routing.filter.FilterUnacceptedException) && header:INBOUND:http.status=404]" doc:name="Catch Exception Strategy">
How ever this is causing an error in my flow when it is hit:

Is there way to implement this type of logic in Mule?
The problem is that you are mixing expression evaluator. Your when clause should look like the following:
<catch-exception-strategy when="#[exception.causedBy(org.mule.api.routing.filter.FilterUnacceptedException) and message.inboundProperties['http.status']=404 ]" doc:name="Catch Exception Strategy">
Here you can find the documentation about MEL
