Question

我正在尝试调试Azure Service Bus。

我做什么：

            long countOpen = namespaceManager.GetQueue(queueStrOpen).MessageCount;
            long countClose = namespaceManager.GetQueue(queueStrClose).MessageCount;
            QClientOpen = QueueClient.CreateFromConnectionString(connectionString, queueStrOpen, ReceiveMode.ReceiveAndDelete);
            QClientClose = QueueClient.CreateFromConnectionString(connectionString, queueStrClose, ReceiveMode.ReceiveAndDelete);


                if (countOpen > 0)
                {
                    QClientOpen.OnMessage(OnMessageOpen,eventDrivenMessagingOptions);
                }
                if (countClose > 0)
                {
                    QClientClose.OnMessage(OnMessageClose,eventDrivenMessagingOptions);
                }

我的错误是什么：

Exception: Microsoft.ServiceBus.Messaging.ServerBusyException: Maximum number of
 concurrent receive requests is exceeded on entity '*****:QUEUE:ORDERSPRAC'.
 The limit is '5000'. Error code : 50004.TrackingId:63eefddf-0503-4c30-a2de-55fe

此错误不会每次都弹出。它有时只是一个错误是捕获（上面的那个）。如何以及为什么会出现此消息而我检查如果我的消息计数大于0。

它不应该进行一次精确的接听电话，但确实如此，并且经过一天和很多IF条件，很多谷歌搜索我都没想到。

Answer 1

你能否分享你为＆＃34; MaxConcurrentCalls＆＃34;设定的价值？ OnMessageOptions中的属性（上面示例中的eventDrivenMessagingOptions）。此选项确定对服务进行的并发接收呼叫的数量。

Azure - 并发呼叫 - 服务总线
