Hi,

Since I never encounter this issue, I try to search the reason and the solution from Internet. Some says, "This problem frequently occurs when your application  performs many string concatenations, such as dynamically building HTML or XML   strings. In this scenario, Aspnet_wp.exe (or W3wp.exe , for applications that   run on IIS 6.0) is the offending process." (http://support.microsoft.com/kb/307340)

Below is some links for you:

Hope these will be helpful.

Because you gave me very limited information, I need more information about your issue so that I can help you further.
