Question

我有一个NServiceBus传奇，试图使用Raven超时持久性来安排超时，但是当它尝试时会出现此错误：

NServiceBus.Unicast.Transport.Transactional.TransactionalTransport [(null)] <(null)> - Failed raising 'transport message received' event for message with ID=90dadfbd-9eb6-4558-96ec-37edb642330a\17275422

我已经重启了Raven服务＆amp; nservicebus主机。我已经尝试重新创建这个传奇但它仍然会发生。

正在安排的超时状态消息很小：

<Messages xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://tempuri.net/Invoicing.Service">

    </IPartPaymentTimeout>

在我的案例中，通过停止自定义应用程序的新Relic来解决这个问题。看起来New Relic中有一个错误，它附加了一个请求标头X-NewRelic-ID，它会附加相同的数据，直到它长得太长：

X-NewRelic-ID: <hash>, <samehash>, <samehash>,.....<samehash>

禁用NewRelic.xml文件中的NServiceBus.Host检测可防止发送标头。

在NewRelic.xml中，您也可以禁用crossApplicationTracingEnabled。

要检测此问题，请使用System.Diagnostics中的跟踪：

  <system.diagnostics>
<trace autoflush="true" />
<sources>
  <source name="System.Net" maxdatasize="1024">
    <listeners>
      <add name="MyTraceFile"/>
    </listeners>
  </source>
</sources>

<sharedListeners>
  <add
    name="MyTraceFile"
    type="System.Diagnostics.TextWriterTraceListener"
    initializeData="System.Net.trace.log"
            />
</sharedListeners>

<switches>
  <add name="System.Net" value="Verbose" />
</switches>

当NServiceBus尝试安排超时时，Raven返回400“请求太长”错误
