'/' 中的服务器错误应用

Question

我有一个使用实体框架的标准 ASP.NET 4 网站。似乎每隔一段时间，我都会遇到致命错误。刷新页面可以，但我知道这不是数据库的问题。该异常似乎是由实体框架引起的，但我不确定如何追踪它。有其他人遇到过这种情况吗？或者有什么方法可以进一步追踪发生的情况吗？

错误是：

Server Error in '/' Application.
A severe error occurred on the current command.  The results, if any, should be discarded.
A severe error occurred on the current command.  The results, if any, should be discarded.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Data.SqlClient.SqlException: A severe error occurred on the current command.  The results, if any, should be discarded.
A severe error occurred on the current command.  The results, if any, should be discarded.

Source Error:

Line 758:                mainImage = Db.ContentImages.FirstOrDefault(i => i.ItemID == itemId && i.t_ItemType == (int) itemType && i.MainImage);
Line 759:                if(mainImage == null) {
Line 760:                    var firstVideo = Db.ContentVideos.FirstOrDefault(i => i.ItemID == itemId && i.t_ItemType == (int) itemType && !string.IsNullOrEmpty(i.PreviewImage));
Line 761:                    if(firstVideo == null) {
Line 762:    

这不仅发生在上述位置，而且在我的所有 EF 代码中随机发生。我什至尝试重新创建 EDMX，但无济于事。
