症状：

如果我等待 15-20 分钟，然后尝试登录我的网站，我会收到以下堆栈跟踪/错误。如果我在大约 20 秒后点击刷新，一切正常。我真的很想让网站停止这样做。

编辑 我是唯一一个认为他或她在提出问题后立即解决问题的人吗？我有一个位于母版页上的 ASP SQLDataSource。我刚刚将其添加到 Selecting 事件中：

If Not System.Web.HttpContext.Current.User.Identity.IsAuthenticated Then
    e.Cancel = True
End If

我会在大约半小时左右后发回结果 - 没有解决问题

/编辑

*edit_2* 这是 SQL 数据源

<asp:SqlDataSource ID="SQLds_ClientSearch" runat="server" ConnectionString="<%$ ConnectionStrings:meta_db_ConStr %>" SelectCommand="Select * from View_Clients WHERE (ClientName LIKE @Search + '%' OR SISAR LIKE @Search + '%') ">
       <SelectParameters>
           <asp:ControlParameter ControlID="Search_tb" Name="Search"
           PropertyName="Text" Type="String" ConvertEmptyStringToNull="False" />
       </SelectParameters>
   </asp:SqlDataSource>

这是我的 web.config 下的连接

<connectionStrings>    
<add name="meta_db_ConStr" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\meta_db.mdf;Integrated Security=SSPI;User Instance=True" providerName="System.Data.SqlClient" />
</connectionStrings>
