SYMPTOMS

When you run the undocumented DBCC PSS or DBCC STACKDUMP command while the server is processing the input buffer for an incoming query, a variety of access violations and 17805 errors may occur. This problem occurs more frequently when an application submits a large remote procedure call (RPC) input buffer, especially when the RPC input buffer is greater than or equal to 8 KB. However, this problem may occur even if the input buffer is less than 4 KB. The following 17805 error message is logged in the error log:
Error: 17805, Severity: 20, State: 3
Invalid buffer received from client..

CAUSE

This problem occurs because of a bug that has been discovered in the undocumented DBCC PSS command that can cause access violations in all versions of Microsoft SQL Server under certain circumstances. This command is used by the following utilities, but it has been corrected:
  • Microsoft SQL Server 2000 Best Practices Analyzer 1.0 Beta
  • Microsoft SQL Server 2000 blocking detection script
  • PSSDIAG For more information about the PSSDIAG utility, click the following article number to view the article in the Microsoft Knowledge Base:
    830232 PSSDIAG data collection utility
See the "Workaround" section in this article for information about how to obtain the updated utilities.

Note This problem does not occur because of these utilities; the problem occurs because of the DBCC PSS command.

WORKAROUND

Until a fix that addresses the problem with the DBCC PSS command is released, Microsoft recommends that you not use this command on production instances of SQL Server. The use of the DBCC PSS command has been removed from these utilities. To work around this problem, use the following information (depending on the utility that you are using):
  • If you are using the SQL Server 2000 Best Practices Analyzer 1.0 Beta, download the latest version immediately. To do so, visit the following Microsoft Web site: http://www.microsoft.com/downloads/details.aspx?amp;displaylang=en&familyid=B352EB1F-D3CA-44EE-893E-9E07339C1F22&displaylang=en
  • If you are using the SQL Server 2000 blocking detection script, obtain the updated script from the following Microsoft Knowledge Base article:
    271509 How to monitor SQL Server 2000 blocking
  • If you are using the PSSDIAG utility, contact Microsoft Product Support Services (PSS) to obtain a version of the tool that does not call the DBCC PSS command. For information about how to contact PSS, visit to the following Microsoft Web site: http://support.microsoft.com/default.aspx?pr=cntactms

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Microsoft SQL Server 2000 Service Pack 4.
