Large Amount of Memory Used on MSSQLSERVER

Error Message​

MS SQL SERVER on the SQL database VM is utilizing a large amount of memory

Description​

The MS SQL Server memory (RAM) increases to an unexpectedly high level.

Possible Causes​

This is not a memory leak but a Microsoft MS SQL Server default setting. MS SQL Server consumes as much memory as Windows allows it to consume. This is a by-design behavior of an MS SQL Server instance and is not a CloudShell issue.

Solution​

To resolve the issue described above, follow these steps:

You can configure the maximum RAM usage on an MS SQL Server Instance to limit its memory consumption to a reasonable level in the following two ways.

note

It is recommended that you refer to the Microsoft website for the most up-to-date instructions.

  1. Via the GUI Interface (MS SQL Server Management Studio).
  2. Via the Standard MS SQL Command Query via a MS SQL session fired up by a programming language or, directly in MS SQL Server Management Studio.
    1. Connect to your target MS SQL Server instance.
    2. Open a new query page, pointing to "master”(one of the System Databases).
    3. Type/Run the following commands, one at a time:
      1. sp_configure 'show advanced options', 1;
      2. GO
      3. RECONFIGURE;
      4. GO
      5. sp_configure 'max server memory', XXXX;  
      note

      "XXXX” can be any number up to 17674, i.e. 17.674GB

      1. GO
      2. RECONFIGURE;
      3. GO
      4. sp_configure 'show advanced options', 0;
    4. Exit MS SQL Server Management Studio (you do not need to save anything).
