Configuring the maximum memory for the management database

Because SQL Server dynamically acquires memory whenever it needs it until it reaches the maximum server memory you have configured, you should set constraints on how much physical memory it should be allowed to consume. You can use the formula described in Configuring the maximum memory for audit store databases to determine the maximum memory you should allow for the Microsoft SQL Server instances hosting the management database.

For more information about how to configure Microsoft SQL Server maximum memory setting and other memory options, see the following Microsoft article:
