缓存超时或不存在
当尝试提交到服务器时，我不断收到以下错误：
Cache timed out or does not exists.
StackTrace:
at Royal4.MP.MasterScheduling.ProgramScheduling.iBtnAdd_Click(Object sender, ImageClickEventArgs e)
at System.Web.UI.WebControls.ImageButton.OnClick(ImageClickEventArgs e)
at System.Web.UI.WebControls.ImageButton.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument)
at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument)
at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData)
at System.Web.UI.Page.ProcessRequestMain()
此错误大约在使用 2-3 分钟后出现，并且似乎总是在对服务器进行某些调用的回发上发生。我想知道是什么导致了这个错误（因为它经常发生并且它阻止了实际发生的更新）。另请注意，当我在本地计算机上运行代码时，我无法复制错误，我只在生产服务器上收到错误。任何帮助表示赞赏。
其他信息：
语言：C# .NET
框架：.NET 1.1
IIS版本：6
服务器：Windows 2003
数据库：Progress 4GL（不要问）
如果需要其他信息，请询问，我会提供尽可能多的信息。
谢谢，

I keep recieving the following error when attempting to submit to the server:
Cache timed out or does not exists.
StackTrace:
at Royal4.MP.MasterScheduling.ProgramScheduling.iBtnAdd_Click(Object sender, ImageClickEventArgs e)
at System.Web.UI.WebControls.ImageButton.OnClick(ImageClickEventArgs e)
at System.Web.UI.WebControls.ImageButton.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument)
at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument)
at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData)
at System.Web.UI.Page.ProcessRequestMain()
This Error shows up roughly after 2-3 minutes of usage and it seems like it is always happening on a postback that is doing some call to the server. I would like to know what is causing this error (because it is happening quite often and it stops the updates from actually occuring). Another note, when I run the code on my local machine, I cannot replicate the error, I only get the error on my production server. Any help is appreciated.
Additional Information:
Langauge: C# .NET
Framework: .NET 1.1
IIS version: 6
Server: Windows 2003
Database: Progress 4GL (Don't ask)
If Additional information is required, just ask, I'll give as much information as i can.
Thanks,
Tim

“缓存超时或不存在。”听起来不像 .NET 错误。我的猜测是它是由您的代码在某处显式抛出的。
在 Royal4.MP.MasterScheduling.ProgramScheduling.iBtnAdd_Click 查看该函数的源代码将有所帮助，因为这似乎是抛出异常的地方。
您的生产环境是网络农场吗？在这些环境下通常会出现缓存问题（因为场中的服务器之间不共享缓存）。
"Cache timed out or does not exists." does not sound like a .NET error. My guess is it's being explicitly thrown by your code somewhere.
It would help to see the source code for the function at Royal4.MP.MasterScheduling.ProgramScheduling.iBtnAdd_Click, as it seems this is where the exception is being thrown.
Is your production environment a web farm? Often caching problems can come up under these environments (since cache is not shared between servers in a farm).
