Request timed out - Request timed out

My website is running on Asp.net v4 , IIS 7 , Windows server 2008.

My cpu is running on 20-30% and the site is responding quickly.

Every 2-5 mins I'm receiving the following error:

Event code: 3001 
Event message: The request has been aborted. 
Exception type: HttpException 
Exception message: Request timed out. , 

Request information: 
    Request URL: http://www.xxxx.com/Services/AxRefresh.asmx/AxUpdate 
    Request path: /Services/AxRefresh.asmx/AxUpdate 
    User host address: 84.110.251.198 
    User:  
    Is authenticated: False 
    Authentication Type:  
    Thread account name: NT AUTHORITY\NETWORK SERVICE 

i read that the error is related to the maximum concurrent requests limit http://support.microsoft.com/kb/821268

but then i found out that on IIS 7 this limitation is changed and not relevant. http://msdn.microsoft.com/en-us/library/dd560842(VS.100).aspx

Any other ideas what can be the problem or w开发者_如何学JAVAhere to start looking ?

update: found another link saying that all the below parameters: maxWorkerThreads minWorkerThreads maxIoThreads minFreeThreads minLocalRequestFreeThreads maxconnection executionTimeout

are NOT relevant for IIS7+Asp.NET 4

here is the link http://learn.iis.net/page.aspx/381/aspnet-20-breaking-changes-on-iis-70

**I still get the 100's errors daily on my iis7 **

The second link you found has no relationship with the first one, so you still need to apply the changes in the first article and see if it helps.
