Question

服务器A和B包含SQL Server实例。有通过TRANSPORT的路线创建服务。 ~~已成功收到消息。我正在尝试在B上创建内部激活，但队列停止。我做错了什么？~~已修复。对于从A发送到B的每条消息，返回5份。

我正在尝试在B上创建内部激活，但队列停止

这很有可能是毒药消息检测。这意味着您的激活过程会引发异常并导致回滚。发生这种情况时，程序的输出（包括错误消息）将记录到ERRORLOG中。这就是你需要看的地方。

您还可以尝试通过禁用激活并从查询窗口手动调用该过程来解决该过程。这样您就可以直接看到任何错误消息/异常。要在与激活过程相同的上下文中执行，请在调用过程之前发出EXECUTE AS USER = 'dbo'。

请参阅Troubleshooting Activation Stored Procedures。
