Bug #: 473585 (SQL Server 8.0)



''Microsoft distributes Microsoft SQL Server 2000 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2000 fix release.''



SUMMARY
This article describes the following about this hotfix release:
 * The issues that are fixed by this hotfix package
 * The prerequisites for applying the hotfix package
 * Information about whether you must restart the computer after you install the hotfix package
 * Information about whether the hotfix package is replaced by any other hotfix package
 * Information about whether you must make any registry changes
 * The files that are contained in the hotfix package



SYMPTOMS
Consider the following scenario. You create a query that uses the UNION ALL operator more than 255 times. You submit this query from a client application to Microsoft SQL Server 2000. In this scenario, a stack overflow exception may occur, and then SQL Server unexpectedly closes. When this problem occurs, the client application receives the following error message:

Server: Msg 8621, Severity 17, State 1, Line 1 Internal Query Processor Error: The query processor ran out of stack space during query optimization.

Additionally, the following error is written to the SQL Server error log:

spid52  Stack Overflow Dump not possible - Exception c00000fd E at 0x00000000005A8C70

spid52 Address=5a8c70 Exception Code = c00000fd

spid52 

spid52

spid52 TotalPhysicalMemory = 2139881472, AvailablePhysicalMemory = 1585553408

spid52 AvailableVirtualMemory = 7677010944000, AvailablePagingFile = 3594182656

On computers that run on the IA-64 architecture, the client application may receive the following error message:

[Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionCheckForData (CheckforData).

Server: Msg 11, Severity 16, State 1, Line 0 General Network Error. Connection broken

Finally, the following error is written to the SQL Server event log: Event type: Error

Event source: Service Control Manager

Event catalog: None

Event ID: 7034

Date:

Time:

User: N/A

Computer:

Description: The MSSQLSERVER service terminated unexpectedly. It has done this 1 time(s).
