akka流不消耗，只记录唤醒时间

我有这个应用程序，我们已经测试了几个月了。通常的设置要么使用嵌入式Kafka，要么使用docker compose中的Kafka。我得承认只有1个分区。一旦我们部署了它（dockerized，连接到一个真正的代理，只有一个），它甚至不会开始消费，而是只记录以下内容：

May  2 10:40:05 ip-10-189-162-144 docker: [WARN] [05/02/2018 10:40:05.533] [KafkaIngester-akka.actor.default-dispatcher-4] [akka://KafkaIngester/system/kafka-consumer-1] KafkaConsumer poll is taking significantly longer (13000ms) to return from poll then the configured poll interval (500ms). Waking up consumer to avoid thread starvation.

正如您所看到的，问题是唤醒超时。我试着增加到13秒，但还是失败了。我试图增加投票间隔，但还是失败了。我们尝试从同一台机器上的docker容器运行telnet kafka 9092，连接被接受。但它什么也不消耗。我们真的不知道为什么。
我的流程是
我的流程是：

val consumerSettings = ConsumerSettings(actorSystem, new StringDeserializer, new ByteArrayDeserializer)
      .withProperties(kafkaProperties)
val source =     Consumer.committableSource(consumerSettings, Subscriptions.topics(topics.toSet)).map { msg =>
      receivedCounter.foreach(_.inc())
      msg
    }

   source
      .mapAsync(maxParallel)(process)
      .mapAsync(maxParallel)(commit).runWith(Sink.ignore)

 def commit(committableMessage: CommittableMessage[String, Array[Byte]]): Future[Done] = {
      errorReporterWaitStrategy.reset()
      processorWaitStrategy.reset()
      committableMessage.committableOffset.commitScaladsl()
    }

def process(msg: MSG): Future[MSG] = {
      receivedCounter.foreach(_.inc())
      innerInvoke(msg)
    }

这是从我的代码的不同部分复制的片段。
