BUG #: 474421 (SQL Server 8.0)

BUG #: 474598 (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 installing the hotfix package
 * Whether you must restart the computer after you install the hotfix package
 * Whether the hotfix package is replaced by any other hotfix package
 * Whether you must make any registry changes
 * The files that are contained in the hotfix package



SYMPTOMS
Microsoft SQL Server 2000 may intermittently appear to stop responding (hang) during a scheduled maintenance DBCC DBREINDEX operation. If you are running SQL Server 2000 in a clustered environment, the clustered SQL Server 2000 resource may go offline because the IsAlive functionality determines that the SQL Server 2000 resource has stopped responding.

Additionally, error messages that are similar to the following may be written to the SQL Server 2000 error log:

Error: 17883, Severity: 1, State: 0

Process 56:1 (56c) UMS Context 0x11761B68 appears to be non-yielding on Scheduler 0.

810185 SQL Server 2000 hotfix update for SQL Server 2000 Service Pack 3 and 3a



CAUSE
This problem occurs if the worker thread that runs the DBCC DBREINDEX operation monopolizes the scheduler. This problem occurs because the index builder thread only yields to other processes after the index builder process has filled approximately 100 extents.
