NServiceBus 启动，短暂运行，然后崩溃

Question

我有一个在使用 NServiceBus 的 Azure VM 上运行的 Windows 服务。当我启动服务时，它会启动，运行一分钟左右然后停止。我能找到的唯一错误日志是在事件查看器中。

Application: NServiceBus.Host.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.Messaging.MessageQueueException
   at System.Messaging.MessageQueue+MQCacheableInfo.get_WriteHandle()
   at System.Messaging.MessageQueue.StaleSafeSendMessage(MQPROPS, IntPtr)
   at System.Messaging.MessageQueue.SendInternal(System.Object, System.Messaging.MessageQueueTransaction, System.Messaging.MessageQueueTransactionType)
   at NServiceBus.Transports.Msmq.MsmqMessageSender.Send(NServiceBus.TransportMessage, NServiceBus.Unicast.SendOptions)

我正在阅读可能关于同一问题的旧帖子，人们说 NServiceBus 可能正在尝试记录错误，但记录器本身失败导致此问题。有没有人以前见过这个或对此有任何见解？谢谢。

在同事的帮助下，我们发现了这个问题。有一个未填充的消息队列变量，并且 NServiceBus 的消息队列名称格式不兼容，导致错误。
