SYMPTOMS

When you open structured storage files by using a third-party program, the computer eventually runs out of virtual address storage space.

CAUSE

This behavior can occur because, depending on which service pack is installed, OLE reserves from 2 to 4 megabytes (MB) of virtual memory for each open file. Service packs allocate 4 MB for each open file; about half of the 2 gigabytes (GB) of user address space is reserved when 250 files are open.

An example of this behavior is that SolidWorks 2000, which is a computer-aided design (CAD) program, runs out of address space because OLE reserves 4 MB of address space for each file, even though the file size is less than 4 MB.

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

STATUS

Microsoft has confirmed that this is a problem in Microsoft Windows 2000. This problem was first corrected in Windows 2000 Service Pack 2.

MORE INFORMATION

If you open more than 250 files, OLE switches to a different scheme that does not use as much memory.
