Question

我有一个应用程序，它使用Microsoft Dynamics CRM的API来插入和更新记录。每当我连续处理少量记录时，我在尝试进行其中一个更新时遇到以下错误：

2013-02-14 10:25:56,382 - Updating lead in dynamics with leadid [3cdaa9d4-c276-e211-99b6-005056ab0822]

在Google上搜索，我发现了可能出现此特定错误（System.IO.IOException: Authentication failed because the remote party has closed the transport stream.）的几个原因，但在所有情况下，由于配置错误或证书损坏，它每次都发生。

世界上有什么可能触发此错误间歇？

它与Web请求的内容无关，因为我可以在5分钟后处理相同的请求并且它可以正常工作。对此服务器的所有请求大约10％的折扣会导致此错误。

编辑：以下是使用SharePoint similar problem的人，但每次都会发生错误。

使用CRM诊断工具打开跟踪日志记录：http://crmdiagtool2011.codeplex.com以查看是否收到任何其他错误信息（假设您正在使用On Premise）。我猜你的CRM服务器到SQL数据库的SQL连接不太对。

是什么导致我间歇性的System.Net.WebException错误？
