BUG: Perfmon Terminates While Monitoring SQL Procedure Cache

• Microsoft SQL Server

SYMPTOMS

If you shut down SQL Server while you are monitoring any SQL Server - Procedure Cache counter in Performance Monitor (Perfmon.exe), Perfmon.exe and Winlogon.exe close with a Divide By Zero Exception error. If you run Perfmon.exe on the Windows NT console, an Unhandled Exception error in SQLCTR60.DLL appears in Perfmon.exe.

If you monitor the counter in Perfmon.exe from a client computer, the Exception error occurs in Winlogon.exe and a STOP: 0xc000021a (Fatal System Error) screen appears.

In addition, the following Application event appears in Event Viewer:

   Event ID: 8
   Source:  SQLCTR60.DLL
   Description: DB-LIBRARY error: Attempt to bind to a non-existent column.
