An "out of memory" error may occur even when there are many free pages in Microsoft SQL Server. Additionally, you receive a message that resembles the following:
date time Failed to allocate reserved pages: FAIL_RESERVED_PAGE_ALLOCATION 1
Note: This is frequently observed when running DBCC CHECKDB, but is not exclusive to this command.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
