| Event Information | According to Microsoft: CAUSE: The system may be configured with a large quantity of physical memory. Tools such as Task Manager and Performance Monitor may indicate that a large portion of that memory is available. For example, if the system is configured with four gigabytes of physical memory, less than one gigabyte of this memory may be in use. However, if the virtual memory for the Internet Information Services (IIS) DLLHost process for Medium Isolation mode approaches two gigabytes, problems start to occur. Even if the server has large memory resources that are available to the system, the virtual memory of the IIS process may become fragmented. Various errors may be reported, indicating that memory resources have been used up. The Commerce Server OLE DB provider typically uses the SQL OLE DB provider to perform database operations. In a large E-Commerce site, the Commerce Profile services must continually retrieve data from the SQL database. The SQL OLE DB provider tries to allocate large contiguous blocks on demand to perform these operations. These allocations are performed in the virtual memory address space of the IIS process. If this process is approaching the process limit for virtual memory that is established by Microsoft Windows 2000, errors result. If no blocks of contiguous virtual memory are available because of fragmentation, the application may return error messages indicating that no memory is available. RESOLUTION: To alleviate these symptoms, the system must be configured to prevent each IIS process from using up the virtual memory that is available. By default, Windows 2000 with IIS 5.0 is configured in Medium Isolation mode. In this configuration, the Commerce 2000 and Web site code use a shared DLLHost process. Use Performance Monitor to make sure that the virtual memory for this process does not approach two gigabytes. |
