| Event Information | If you try to copy a file that is larger than 100 megabytes (MB) to a server location by using the Web Distributed Authoring and Versioning (WebDAV) service, you receive the following error message: Windows - Delayed Write Failed You also receive the following event ID: Event ID 14800 "Windows was unable to save data for file <file_name>. The data has been lost. This error may be caused by a failure of your computer or network connection. Please try to save this file elsewhere. CAUSE : This problem occurs because, during a WebDAV connection, the WinInet function does not break up the data into sufficiently small chunks. As a result, the system cannot allocate a sufficiently large block of kernel pool memory, and therefore the file-copy operation is unsuccessful. RESOLUTION : A supported fix is now available from Microsoft. |
