OnMessageAsync（）并不总是触发

Question

以下是我的Azure Service Fabric Service Bus队列侦听器的确切代码。 我遇到的问题是_client.OnMessageAsync“休息”时不使用几分钟。它最终会在5分钟内唤醒并处理排队的消息。消息永远不会丢失或死亡，但这是不可接受的行为。我试过调整消息选项，但是nada ..

有什么想法吗？

 internal sealed class Core : StatelessService
    {
        readonly QueueClient _client;
        readonly OnMessageOptions _msgOptions;

        public Core(StatelessServiceContext context)
            : base(context)
        {
            var connectionString = CloudConfigurationManager.GetSetting(Resources.ServiceBusConnectionString);
            var inQueue = CloudConfigurationManager.GetSetting(Resources.InQueue);
            var factory = MessagingFactory.CreateFromConnectionString(connectionString);
            _client = factory.CreateQueueClient(inQueue, ReceiveMode.PeekLock);
            _msgOptions = new OnMessageOptions
            {
                AutoComplete = false,
                MaxConcurrentCalls = 5

            };
        }

        protected override IEnumerable<ServiceInstanceListener> CreateServiceInstanceListeners()
        {
            return new ServiceInstanceListener[0];
        }
        protected override async Task RunAsync(CancellationToken cancellationToken)
        {
            await Task.Run(() =>
            _client.OnMessageAsync(
              async message =>
              {
                  OnReceived(message);
                  await message.CompleteAsync();
              }, _msgOptions),
              cancellationToken);
        }
        private void OnReceived(BrokeredMessage brokeredMessage)
        {
            var message = brokeredMessage.GetBody<Message>();
            ServiceEventSource.Current.ServiceMessage(Context, "Working-{0}", message.Transaction.Id);
            var preocessor = new Processor();
            preocessor.Process(message);
        }


    }
