System.OutOfMemoryException in Timesheet Approval

[Rickard]

Using Project Server 2007 + SP2 + April 2009 CU.
My customer use to view his resource's timesheets in Approvals -> Timesheet
in the PWA. But often when he has opened a resource's timesheet and clicked
on the Cancel button the following error appears:

"Exception of type 'System.OutOfMemoryException' was thrown.
Troubleshoot issues with Windows Sharepoint Services."

Now when he tries to open Approval -> Timesheet the error message keep
showing up. What's even more strange is that if he waits until the next day
and try again the error is gone ! I can't find any errors in the server logs.
Has anyone else experienced this issue?

I am getting the same problem. The only solution I can find is a workaround
that relates to Project Server 2003:
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 "Configuring Servers for Applications"
topic in the Server Administration Guide of the IIS 6.0 documentation. To
view the IIS 6.0 documentation, visit the following Microsoft Web site:
