I use IIS 6 width 3 versions of .NET (1.1.4322 , 2.0.50727 , 4.0.30319) on Windows Server 2003 SP2
Most of my websites are run under .NET 2 and share a same pool
I have one website that run under .NET 4 and I have created a separate pool for it and it seem to run fine. But sometime its stop and throw me a error page:
The web application you are attempting to access on this web server is currently unavailable. Please hit the "Refresh" button in your web browser to retry your request.
Administrator Note: An error message detailing the cause of this specific request failure can be found in the application event log of the web server. Please review this log entry to discover what caused this error to occur.
I look in Event Viewer and found it:
Source: ASP.NET 2.0.50727.0
Description: It is not possible to run two different versions of ASP.NET in the same IIS process. Please use the IIS Administration Tool to reconfigure your server to run the application in a separate process.
Please tell me what I should do?

Mm... you already have a new app pool for it, right? is the new app running on the new app pool ?
from the log it is still saying v2 framework.

Thanks for your quick responce, qbernard
Yes, I have created a new pool for this app, and is running on the new pool, on .NET 4. But the error still appear after time. I dont understand why the log say that .NET 2 cause the error

any pattern in specific?
as posted if you manually recycle the app pool, you got this error? try the v2 shared app pool.
