FIX: Terminating Clients with TSQL KILL May Cause ODS AV

ID: Q238620

The information in this article applies to:

Microsoft SQL Server version 6.5

BUG #: 18736 (SQLBUG_65)

SYMPTOMS

Using the Transact-SQL KILL statement to terminate a SQL Server server process ID (SPID) that originated from a TCP/IP Net-Library client can result in a handled access violation (AV) within Open Data Services (ODS), which results in a shutdown of SQL Server.

When such an ODS AV occurs, you can see the following stack dump output in the error log:

server ***********************************************************
server *
server * STACK DUMP:
server *
server * Exception Address = 25A21960

RESOLUTION

A supported fix that corrects this problem is now available from Microsoft, but it has not been fully regression tested and should be applied only to systems experiencing this specific problem. If you are not severely affected by this specific problem, Microsoft recommends that you wait for the next SQL Server service pack that contains this fix.
