Bug #: 469882 (SQL Server 8.0)



SYMPTOMS
If you use a program that uses Performance Data Helper (PDH) APIs to collect the performance data of several instances of Microsoft SQL Server 2000 at the same time, an access violation may occur. For example, this problem occurs if you collect performance data from six or more instances of SQL Server. The performance data collection for the instances of SQL Server may also stop. Additionally, you may notice that the following registry key is created and the value of the registry key is set to 1:

Note The registry key is created for all the instances of SQL Server where the performance data is collected.

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.

This problem was first corrected in Microsoft SQL Server 2000 Service Pack 4.



MORE INFORMATION
This problem mostly occurs when you use many SQL Server performance counters to collect the performance data of six or more instances of SQL Server. For example, the problem occurs when you use 30 SQL Server performance counters to collect the performance data for each of seven instances of SQL Server.

This problem does not occur when you try to collect the performance data by using the same SQL Server performance counters and the Performance Monitor program (Perfmon.exe). For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
