SYMPTOMS

If you try to connect to SQL Server 2000 Analysis Services and you have installed Analysis Services Service Pack 3 (SP3), the connection fails. You may receive one of the following error messages:
Cannot open connection to Analysis server '<Server Name>'.
Timeout occurred.
-or-
Unable to open connection.
The operation requested failed due to timeout
-or-

In the Application Event Log:
The memory conservation threashold was exceeded by more than 12.5 percent for an extended period.

CAUSE

This problem occurs because in Analysis Services SP3, the connections to Analysis Services services are blocked when the memory that the msmdsrv process uses exceeds 112.5 percent of the memory conservation threshold value (HighMemoryLimit).

WORKAROUND

To work around this problem, set the memory conservation threshold to a value that is greater than the memory that the msmdsrv process uses. To set the memory conservation threshold, modify the HighMemoryLimit registry key value. To do so, follow these steps.

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

Note Before you follow these steps, make a note of the memory that the msmdsrv process uses immediately after you start Analysis Services.
  1. Click Start, and then click Run.
  2. Type regedit, and then click OK.
  3. Locate the following registry key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\OLAP Server\CurrentVersion

  4. In the right pane, double-click HighMemoryLimit.
  5. In the Edit DWORD Value dialog box, click Decimal.
  6. In the Value data box, type a value that is greater than the memory that the msmdsrv process uses, and then click OK.
  7. Quit Registry Editor.
Note If Analysis Services is enabled to use 3 gigabytes (GBs) (that is, the /3GB switch is enabled in the Boot.ini file), set the memory conservation threshold to a decimal value of 2778726400.
