假定重启后，Asp Mvc应用程序在应用程序中抛出服务器错误'/'

Question

好的，现在已经沉思了几个小时，但我似乎无法掌握它。

我有一个ASP MVC应用程序，在单独放置5-10分钟后会在应用程序错误中抛出服务器错误'/'。我认为这是由于在应用程序池回收后重新加载配置的问题，但是我在IIS上禁用了该功能，问题仍然存在。奇怪的是，如果你刷新页面，它工作正常。

这是堆栈跟踪（应用程序名称替换为TEST_APP）：

任何想法的人？

修改 我已经尝试评论出这种特殊的方法，但它只是在下面的数据库调用中跳转。这就像它需要第一个错误来建立连接

编辑2：示例连接

  using (DBDataContext test_context = new DBDataContext ())
  {
    var result = (from a in test_context.GetTable<test_table>()
                 select a).FirstOrDefault();
    if (result != null)
    {
        // Do Foo
    } 
  }

我认为应该有代码重置您的应用连接字符串。
