Rule Name

A significant portion of the database buffer cache has been written out to the system paging file. This may result in severe performance degradation.

This Warning event indicates that a large portion of the database buffer cache is being written to the system paging file. This issue may indicate that you do not have enough memory installed on the computer. The minimum amount of RAM that is required for a multi-role server is 8 gigabytes (GB).

Determine whether enough memory is installed on the server. Add more memory if it is required.

Verify that the system page file is set correctly. The page file size minimum and maximum must be set to the amount of physical RAM plus 10 MB.

For more information about multiple server roles and hardware requirements, see Understanding Multiple Server Role Configurations in Capacity Planning.

If you are not already doing so, consider running the Exchange tools, which have been created to help you analyze and troubleshoot your Exchange environment. These tools can help make sure that your configuration aligns with Microsoft best practices. They can also help you identify and resolve performance issues and improve mail flow.
