This article has been archived. It is offered "as is" and will no longer be updated.
Bug #: 470146 (SQL Server 8.0)
Microsoft SQL Server 2000 fixes are distributed 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.
Symptoms
Under stress conditions, when you try to run concurrent transactions on a heap (a table that does not have a clustered index defined) and the heap has at least one nonclustered index defined on it, the following error message may be logged in the SQL Server error log file:
2003-08-02 18:07:30.56 spid70 Error: 644, Severity: 21, State: 5
2003-08-02 18:07:30.56 spid70 Could not find the index entry for RID '3610200101a0169267dd448e943b84afe8b8bea25' in index page (1:308117), index ID 2, database 'Database Name'..
Additionally, you may notice the following stack dump file when you start SQL Server 2000 with the -y644 startup parameter:
