    My configuration : SQL Server 2005 x64 Enterprise Edition, 16 GB physical memory.

    Today, I :

    1. Set its Min. Memory : 2 GB, Max Memory : 14 GB

    2. Used gpedit.msc to enable Lock Page

    3. Restarted the SQL Server Service

    4. I got these message in the ERRORLOG file :

    2010-08-19 12:56:27.79 Server Large Page Extensions enabled.

    2010-08-19 12:56:27.79 Server Large Page Granularity: 2097152

    2010-08-19 12:56:45.38 Server Cannot use Large Page Extensions: Failed to allocate 32MB

    2010-08-19 12:57:03.15 Server Using locked pages for buffer pool.

    5. What is "Cannot use Large Page Extensions: Failed to allocate 32MB" ?

    6. Is it a serious error ? How can I fix it ?

    No. not helpful to me.

    I still have these questions :

    1. Do I need to handle this "Cannot use Large Page Extension" error ?

    2. Or just ignore it ?

    3. Is Lock Page always coming with "Large Page Extension" ?

    4. Can I just enable Lock Page but not "Large Page Extension" ?

    5. Is this "Cannot use Large Page Extension" error harmful to my SQL Server ?
