SYMPTOMS

Virtual memory utilization of the aspnet_wp process may increase steadily until Microsoft Internet Information Services 6.0 (IIS) recycles the process. You can monitor this process by viewing the virtual byte utilization in Perfmon. The virtual byte utilization should not continually increase. When this problem occurs, the virtual byte utilization approaches the 2 gigabyte (GB) or 3 GB limit that is configured for a Microsoft Windows Server 2003 process.

CAUSE

The Profile service is leaking multiple Rockall heaps. This problem may occur if a site refresh task is updating critical Web files such as the Global.asax file and the Web.config file. The update causes an IIS 6.0 application domain reset. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
