FIX: The DBCC PSS Command may cause access violations and 17805 errors in SQL Server 2000

This article has been archived. It is offered "as is" and will no longer be updated.
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.
