Bug #: 235062 (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
When an instance of Microsoft SQL Server 2000 runs many parallel query processing operations on a multiprocessor computer, an access violation exception may occur. Typically, these symptoms have been reported on computers with 16 or more processors. However, you may experience this problem on computers with fewer than 16 processors. When the access violation occurs, you may notice stack information in the SQL Server error log file that is similar to the following: --- 000F8) uctor'+0000000B) 00118) 001F) ---
