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，在尝试进行其中一个更新时都会遇到以下错误：

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

世界上有什么可能会间歇性地触发这个错误？

它与网络请求的内容无关，因为我可以在 5 分钟后处理相同的请求并且它会起作用。对此服务器的所有请求大约 10% 的折扣会导致此错误。

编辑：这里有人在使用 SharePoint 时遇到类似问题，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查看您是否获得任何其他错误信息（假设您使用的是 On Premise）。我猜您从 CRM 服务器到 SQL 数据库的 SQL 连接有些不太对劲。
