nservicebus - 使用 NServiceBus 发送消息时出现奇怪的间歇性错误

Question

我们在 NServiceBus 代码堆栈跟踪的日志中看到非常奇怪的间歇性错误

我们使用的 NServiceBus 版本是 3.3.4

这里是错误的堆栈跟踪：

System.ArgumentException: An item with the same key has already been added.
   at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)
   at NServiceBus.MessageHeaders.MessageHeaderManager.NServiceBus.MessageMutator.IMutateOutgoingTransportMessages.MutateOutgoing(Object[] messages, TransportMessage transportMessage)
   at NServiceBus.Unicast.UnicastBus.InvokeOutgoingTransportMessagesMutators(Object[] messages, TransportMessage result)
   at NServiceBus.Unicast.UnicastBus.MapTransportMessageFor(Object[] rawMessages, TransportMessage result)
   at NServiceBus.Unicast.UnicastBus.SendMessage(List`1 addresses, String correlationId, MessageIntentEnum messageIntent, Object[] messages)
   at NServiceBus.Unicast.UnicastBus.SendMessage(Address address, String correlationId, MessageIntentEnum messageIntent, Object[] messages)
   at NServiceBus.Unicast.UnicastBus.NServiceBus.IBus.Send(Object[] messages)

任何想法是什么问题？我们的生产代码有时会因此而失败，我们需要知道原因。

谢谢。任何帮助，将不胜感激。
