我有一个 NServiceBus 传奇，它尝试使用 Raven 超时持久程序安排超时，但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

我已重新启动 Raven 服务和 nservicebus 主机。我尝试再次重现这个传奇故事，但它仍然发生。
正在安排的超时状态消息很小:

最佳答案
在我的案例中，这个问题是通过阻止 New Relic 安装自定义应用程序来解决的。 New Relic 中似乎存在一个错误，它会附加请求 header X-NewRelic-ID ，它会附加相同的数据，直到它变得太长:
X-NewRelic-ID: <hash>, <samehash>, <samehash>,.....<samehash>
在 NewRelic.xml 文件中禁用 NServiceBus.Host 的检测会阻止发送 header 。
在 NewRelic.xml 中，您还可以禁用 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>
关于ravendb - 当 NServiceBus 尝试安排超时时，Raven 返回 400 "Request Too Long"错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/14313800/
