Web 服务器 - 信号量超时期限已过

【中文标题】Web 服务器 - 信号量超时期限已过

【英文标题】：Web Server - The semaphore timeout period has expired

【发布时间】：2014-09-24 23:05:07

【问题描述】：

尝试在 Windows Server 2008 R2 上运行 Web 应用程序时出现以下错误。当应用程序尝试连接到数据库时出现此错误。但是，我可以在另一台 Web 服务器（Windows Server 2008 R2）上运行该应用程序而不会出现任何问题。

我看到有很多关于这个错误的帖子，但我无法为我找到解决方案。

任何帮助将不胜感激。

【问题讨论】：

***.com/questions/13999439/…

您的连接字符串是否包含 Connection Timeout=XX; ？如果不尝试添加，如果有，尝试将 XX 的值增加到 60

这个错误总是发生吗？在什么情况下会发生？网络有多稳定？

发生此错误时 SQL Server 错误日志显示什么？

你找到解决办法了吗？
