CreateFileMapping or CreateFileForMapping APIs Do Not Succeed on Large Remote Files, Return 'Out of Memory' Error (328945)


The information in this article applies to:

  • Microsoft Windows CE .NET 4.0
This article was previously published under Q328945

SYMPTOMS

If you try to create a file mapping over a redirector network connection, you are unsuccessful. The CreateFileMapping API or the CreateFileForMapping API returns an "out of memory" error when you try to map a remote file that is larger than available memory. This probrem occurs even if you ask for a paged mapping.

CAUSE

Code added to validate a read buffer in the redirector component is unsuccessful when the kernel checks whether the redirector supports paged file access. This causes the kernel to try to load the whole file into memory; this attempt is unsuccessful if the file size is greater than available RAM. Not all media sources can support paged mapping. In this case the TCP/IP redirector incorrectly reports that it cannot support paged mapping.

RESOLUTION

A supported fix is now available from Microsoft as Windows CE 4.0 Core OS QFE Q328945. To resolve this problem immediately, search for the keyword "QFE" on the following Microsoft Web site:
