Hi Experts,

We have a new SQL Cluster built. Windows 2008 R2/ SQL Server 2005 SP3 with 96 GB RAM.

It is not in production and was a fresh install.

I limited SQL Server to 90 GB RAM and see this error in the error log:

A significant part of sql server process memory has been paged out. This may result in a performance degradation.

Any idea why this occurs and how to resolve.

Thanks,

To fix this you should just need to assign the "Lock Pages in Memory" attribute to the service account that SQL Sevrer is running under. You can do this in secpol.msc.

This is pretty standard. I would also make sure that you set your memory limits too though. Ie min server memory & max server memory. These settings are both in SQL. Otherwise it will be possible for SQL Server to all memory and not give anything back to the os.

Hi

You don't mention if you are running in X32 or X64?
Set the service account to lock pages in memory and then enable AWE on the sql.
