WORKAROUND
To work around this problem, change the join type in the query from a hash join to a merge join.
For more information about hash joins and merge joins, see the "Advanced Query Tuning Concepts" section in the SQL Server Books Online.

STATUS
Microsoft has confirmed that this is a bug in the Microsoft products that are listed in the "Applies to" section.
back to the top
MORE INFORMATION
This problem occurs after a period of 60 seconds or more. After this time, the system server process ID (SPID) that performs the hash operation does not yield control of the User Mode Scheduler (UMS). This behavior can cause query delays and timeouts. Also, users cannot log on.
Typically, this problem occurs with SQL Server 2000 when it is on a computer that is running Microsoft Windows Server 2003, Enterprise Edition for Itanium-based Systems. However, this problem may occur with SQL Server 2000 on a computer that is running the 32-bit versions of Microsoft Windows 2000 or Windows Server 2003 with a smaller number of rows and a smaller number of hash memory grants.
To determine whether you are experiencing this problem, use SQL Profiler. To do this, follow these steps:
- Click Start, point to All Programs, point to Microsoft SQL Server, and then click Profiler.
- On the File menu, point to New, and then click Trace.
- In the Connect to SQL Server dialog box, click the computer that is running SQL Server 2000 that you want in the SQL Server list, choose the authentication option that you want, and then click OK.
- On the Events tab, expand Errors and Warnings, click Hash Warning, and then click Add.
- On the Data Columns tab, click IntegerData in the Unselected data list, and then click Add.
- In theUnselected data list, click EventSubClass, and then click Add.
Note The IntegerData column will provide the node ID. The EventSubClass column will provide the subevent that may return a hash recursion or a hash bailout.
- Click Run to run the trace.
