WORKAROUND

To work around this problem, use one of the following methods:
  • Disable parallelism for the specific query by using the OPTION (MAXDOP 1) clause.

    -or-
  • Disable parallelism server-wide by setting the sp_configure parameter max degree of parallelism to 1.

    -or-
  • Use trace flag 683 that in included in SQL Server Post SP3 hotfix builds 8.00.0765 and later. If you enable this trace flag, the pre-SQL Server 2000 SP3 parallel scan behavior is enabled, and the access violation does not occur.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Microsoft SQL Server 2000 Service Pack 4.
