是什么导致我的间歇性System.Net.WebException错误？

我有一个应用程序使用Microsoft Dynamics CRM的API来插入和更新记录。每当我连续过程的记录屈指可数，我打了以下错误试图使更新之一时：是什么导致我的间歇性System.Net.WebException错误？

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

谷歌搜索的时候，我发现为什么这个错误（System.IO.IOException: Authentication failed because the remote party has closed the transport stream.）可能occurr有几个原因，但在所有情况下，由于配置错误或证书损坏，每次发生时，都会发生此问题。

什么在世界上可能触发这个错误间歇？

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，并且它可以工作。对此服务器的所有请求约有10％会导致此错误。

编辑：这里有人用similar problem使用SharePoint，但每次都发生错误。

什么版本的CRM？数据块传输有多大？ – 2013-02-15 06:53:30

之间有什么东西（代理，防火墙，...）？ – ccellar 2013-02-15 10:11:04

你是不是在多个线程之间共享上下文/ IOrganization服务？ – Daryl 2013-02-15 11:52:28

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SQL连接从你的CRM服务器到SQL数据库有一些不太正确的地方。

我会试试这个。谢谢达里尔。 – 2013-02-16 02:34:00

虽然我得到的错误似乎是在调用服务器和CRM REST API之间的网络层 - 而不是数据库层。 – 2013-02-16 02:39:49
