SimpleRabbitListenerContainerFactory consumer disappeared

I discovered a lot of messages in two queues ('MeasuringMessageConsumer.raw.realtime' and 'MeasuringMessageConsumer.cooked.eigenvalue') that can't consume from our RabbitMQ server in the morning today. Further, on the RabbitMQ management web page, the number of consumers is zero in the two queues(1. The number of consumers in the other queues is not zero. 2. The consumer-application was running.).
To figure it out I made a snapshot of the application stack and output to the file stack-snapshoot-1.txt . After that, I restarted the application, made a snapshot again, and output to the file stack-snapshoot-2.txt.
In the file 'stack-snapshoot-1.txt', without any text 'MeasuringMessageConsumer.raw.realtime' or 'MeasuringMessageConsumer.cooked.eigenvalue', But 'stack-snapshoot-2.txt' does.

Key codes:

   ...
   static final String  RABBIT_LISTENER_ID_RAW_REALTIME = "MeasuringMessageConsumer.raw.realtime";
   ...
   @Bean(name = "customFactory")
    RabbitListenerContainerFactory getFactory(ConnectionFactory connectionFactory)
    {
        SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();
        factory.setConnectionFactory(connectionFactory);
        factory.setPrefetchCount(prefetchCount);
        factory.setBatchSize(batchSize);
        factory.setConsumerBatchEnabled(true);
        factory.setBatchListener(true);
        factory.setMaxConcurrentConsumers(8);
        factory.setConcurrentConsumers(4);
        factory.setAcknowledgeMode(AcknowledgeMode.AUTO);
        return factory;
    }
    ...
    @RabbitListener(
            id = RABBIT_LISTENER_ID_RAW_REALTIME,
            queuesToDeclare = {@Queue(value="${rabbitMQ.consumer.queues.raw.realtime}",durable = "true")},
            autoStartup = "false",
            containerFactory = "customFactory"
    )
    @RabbitHandler
    public void handleRawRealtimeMessage(List<String> messages)
    {
         ...
    }

    ...
    registry.getListenerContainer(RABBIT_LISTENER_ID_RAW_REALTIME).start();
    ...

It is impossible to help diagnose such a problem with just stack traces; you need to provide logs too.

Also, your information is incorrect; the first dump does contain cooked.eigenvalue and raw.realtime, but the second does not.

This is unlikely a problem with the framework; perhaps something stopped those containers.

I can't search for any text about 'cooked.eigenvalue' in the file 'stack-snapshoot-1.txt', are you looking in the file 'stack-snapshoot-2.txt'?

We removed the log files before this posting, So, I can't for you the log files.
Since each consumer is a thread, so each consumer should have a corresponding thread. From 'stack-snapshoot-1.txt', it is not guaranteed.
