我们有一个网站设置，使用WCF与我们的Microsoft CRM 2011解决方案进行通信。
用户在我们的网站上创建新案例，这些案例存储在CRM解决方案中。使用WCF，它调用CRM并存储数据。
这完美无缺，但每天有几次出现以下错误。我们找不到关于这些事件的任何独特之处：随机用户，随机输入等。对于收到错误的用户来说，似乎没有什么是独一无二的。
我们可以在IIS事件查看器中看到错误每天发生3次，具体取决于我们在线用户的数量。
有什么想法吗？什么是独一无二的？提示？什么东西？ :-)谢谢！
错误：
Exception information:
Exception type: SecurityNegotiationException
Exception message: Secure channel cannot be opened because security negotiation with the remote endpoint has failed. This may be due to absent or incorrectly specified EndpointIdentity in the EndpointAddress used to create the channel. Please verify the EndpointIdentity specified or implied by the EndpointAddress correctly identifies the remote endpoint.

我们有1个生产网站服务器和CRM服务器。没有负载均衡器或其他任何东西。

答案 0 :(得分：1)
答案非常有趣。我们发现我们公司的一个团队不时对我们的CRM系统进行了一些非常繁重的测试。这阻止了我们的通话并导致超时。
这也可以解释行动的随机性。
我们通过在计算机上启用跟踪发现，因此我们可以看到性能图表。
