SYMPTOMS
In Microsoft Office SharePoint Portal Server 2003 and in Microsoft Windows SharePoint Services, when you try to access a Web page on the site, you may receive the following error message:

Server Error in '/' Application

Exception of type System.OutOfMemoryException was thrown.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.OutOfMemoryException: Exception of type System.OutOfMemoryException was thrown.

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Stack Trace:

[OutOfMemoryException: Exception of type System.OutOfMemoryException was thrown.]



CAUSE
This problem may occur in situations where the server is under a heavy load. For example, this problem may occur if the portal contains more than 100 subsites, and one or more Web pages that are contained in each of the 100 subsites is accessed at the same time.



WORKAROUND
To work around this problem, configure the MSSharePointPortalAppPool application pool to use more than one Microsoft Internet Information Services (IIS) Worker Process (W3wp.exe). For example, if your portal contains 120 subsites, configure the MSSharePointPortalAppPool application pool to use one worker process for each group of 30 subsites. Therefore, the MSSharePointPortalAppPool application pool uses four IIS worker processes.

For more information about how to configure a Web garden in Microsoft Internet Information Services 6.0 (IIS 6), where an application pool uses more than one worker process, see the &quot;Configuring Servers for Applications&quot; topic in the Server Administration Guide of the IIS 6.0 documentation.

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
