php-amqplib / rabbitmq-bundle消费者不要关闭

Question

我在Symfony 4中使用了php-amqplib / rabbitmq-bundle的这种配置。但是 stat 消费者在29分钟50秒后没有关闭，该如何解决？

batch_consumers:
    stat:
        connection: default
        exchange_options:
            name: stat-exchange
            type: direct
        queue_options:
            name: stat-queue
        callback: StatConsumer
        qos_options:
            prefetch_count: 100
        graceful_max_execution:
            timeout: 1790 # 29min 50sec
