ASP.NET MVC3中的随机会话超时

i have an application which gets random session timeouts. (IIS 7.5 on Windows 2008 R2, .NET 4.0)

我有一个应用程序,可以获得随机会话超时。 (Windows 2008 R2,.NET 4.0上的IIS 7.5)

i tried the following:

我尝试了以下内容:

checked the application log if the w3wp.exe process was crashed, but there is no entry.

如果w3wp.exe进程崩溃,则检查应用程序日志,但没有条目。

disabled in the application pool the rapid fail protection

在应用程序池中禁用快速失败保护

moved to the sql server state provider to be sure the loadbalancers sticky session is not the problem. (we use a kemp loadmaster).

移动到sql server状态提供程序,以确保loadbalancers粘性会话不是问题。 (我们使用kemp loadmaster)。

ensured that no other applications use the same application pool.

确保没有其他应用程序使用相同的应用程序池。

checked that exceptions in a thread of a called assembly is correctly handled. (simulated using throw new exception) and the error handling was correct.

检查是否正确处理了被调用程序集的线程中的异常。 (使用throw new exception模拟)并且错误处理是正确的。

ensured that the validationKey and decryptionKey is set in the webconfig on all 4 webservers to the same key.

确保在所有4个Web服务器上的webconfig中将validationKey和decryptionKey设置为相同的密钥。

i run now out of ideas how to spot this evil bug. any suggestions? i cannot reproduce the problem on my local machine in the debugger.

我现在运行的想法如何发现这个邪恶的错误。有什么建议么?我无法在调试器中重现本地计算机上的问题。

one point which is maybe important, the move from page 1 to page 2 where the session loss often happens, takes sometimes more than 120 seconds, because of a third party system which is connected via tcp socket.

可能很重要的一点是,从第1页到第2页的转移经常发生会话丢失,有时超过120秒,因为第三方系统通过tcp套接字连接。

I am curious if it is MVC 3.0 problem with .net 4.0 as i have several very similar apps running using MVC 2.0 with no problems, Only started when I moved to MVC 3.0

我很好奇,如果它是.net 4.0的MVC 3.0问题,因为我有几个非常相似的应用程序使用MVC 2.0运行没有问题,只有当我转移到MVC 3.0时才开始

Does it happen on a single server? Sure sounds like an issue with the web-farm.

它是否发生在一台服务器上?当然听起来像网络农场的问题。

Can you alter your app so you don't use the 3rd-party app for testing?

您可以更改您的应用程序,以便不使用第三方应用程序进行测试吗?

You have to eliminate pieces until the failure goes away, then add stuff back. Restore 3rd party app, turn other servers back on, etc.

你必须消除碎片,直到失败消失,然后再添加东西。恢复第三方应用,重新打开其他服务器等。
