sql-server – 在Hyper-V中运行SQL Server时“等待操作超时”

我在Hyper-V实例上运行sql Server(2012).它拥有充足的资源和25％的资源总量,VHD放置在速度非常快的SSD驱动器上,可以快速响应.

每隔一段时间,当使用sql Server的应用程序暂时无法访问时,会出现错误“等待操作超时”.当重新加载或重试访问数据库时,它似乎已“被唤醒”并且一如既往地快速.

有没有办法确保在这种环境下不会出现这种软睡眠模式？

添加

异常详细信息：System.ComponentModel.Win32Exception：等待操作超时

解决方法

尝试执行此命令：

exec sp_updatestats

令人难以置信的是,它解决了这个问题.

在执行命令之前的代码上面的错误.
