How to Suppress Memory Configuration Notification Event

 

Topic Last Modified: 2005-05-10

Exchange performs an optimal memory configuration check when the Microsoft Exchange Information Store service (store.exe) starts. If the service detects that the server's configured memory settings are not optimal, Event 9665 will be logged in the application event log. This event typically appears in the following instances:

  • The server is running a Windows 2000 Server family product and the SystemPages value in the registry is set outside the range of 24,000 to 31,000.
  • The server has 1 GB of memory or more but does not have the /3GB startup switch set in its Boot.ini file.
  • The server is running Windows Server 2003, has 1 GB of memory or more and the /3GB switch is set, but the /USERVA setting is not present or does not equal 3,030.

If Event 9665 does appear in the application event log, check the SystemPages and HeapDeCommitFreeBlockThreshold registry settings, and ensure that the /3GB and /USERVA=3030 startup switches are present in the Boot.ini file.

noteNote:
The SystemPages registry entry applies only to Windows 2000. Do not set this value on a Windows Server 2003 computer. The memory configuration check does not occur on servers running Microsoft Small Business Server.

If you are confident that your server is optimally configured and you want to prevent Event 9665 from being logged, you can use the following registry value to suppress logging of Event 9665.

Before you perform the procedure in this topic, be aware that the procedure contains information about editing the registry.

CautionCaution:
Incorrectly editing the registry can cause serious problems that may require you to reinstall your operating system. Problems resulting from editing the registry incorrectly may not be able to be resolved. Before editing the registry, back up any valuable data.

  1. Open a registry editor, such as Regedit.exe or Regedt32.exe.

  2. Navigate to: HKLM\System\CurrentControlSet\Services\MSExchangeIS\ParametersSystem.

  3. Right-click ParametersSystem and select New | DWORD Value.

  4. Name the new DWORD value Suppress Memory Configuration Notification.

  5. Double-click Suppress Memory Configuration Notification to edit its value data.

  6. In the Value data field, enter 1.

  7. Click OK to save the change, and then close the Registry Editor.

  8. Restart the Microsoft Exchange Information Store service for the change to take effect.

For information about how to edit the registry, see Microsoft Knowledge Base article 256986, "Description of the Microsoft Windows Registry," (http://go.microsoft.com/fwlink/?linkid=3052&kbid=256986).
