SQL Server Q&A

Symptoms
Consider the following scenario. In Microsoft SQL Server 2005, you try to run a SQL Server Integration Services (SSIS) package. The SSIS package transfers data between two instances of SQL Server 2005. In this scenario, you may receive an access violation error message. When this problem occurs, the Microsoft Windows Application log contains an event that documents the system error message. The system error message resembles the following:

DTExec.EXE – Application ErrorThe exception unknown software exception (0×40000015) occurred in the application at location 0×7ee8bd9e.Note This problem occurs when Lookup transformations that are in the SSIS package are executed in parallel.This problem does not occur when Lookup transformations that are in the SSIS package are executed sequentially.
Resolution
This problem occurs when Lookup transformations from multiple data flow tasks share the same cache area.Lookup transformations may share the same cache area when the textin the SQLCommand property of one Lookup transformationthat isin a data flow taskis the same asthe textin the SQLCommand property of a Lookup transformationthat is in another data flow task.

Symptoms
When you attempt to shrink a database, SQL Server might stop with a Fatal Exception, multiple 816 errors, and a stack dump in the errorlog.
Resolution
Microsoft has confirmed this to be a problem in SQL Server 7.0. This problem has been corrected in U.S. Service Pack 2 for Microsoft SQL Server 7.0. For more information, click the following article number to view the article in the Microsoft Knowledge Base:

Symptoms
Resize is an internal class method that is used to resize an array. PvReplace may incorrectly use the Resize method leading to an exception.
The following, or similar, top of the stack is logged in the SQL Server error log when the problem occurs:

0×0051ea81 Module(sqlservr+11ea81) (CQDynArray::Resize+69)
0×0043acc7 Module(sqlservr+3acc7) (CQDynArray::PvReplace+2e)
.
Resolution
Microsoft has confirmed this to be a problem in SQL Server7.0. This problem has been corrected in U.S. Service Pack 3 for Microsoft SQL Server 7.0. For more information, click the following article number to view the article in the Microsoft Knowledge Base:

Symptoms
Inserting certain Unicode strings into a SQL Server 2000 Windows CE (SSCE) table might cause an SQL INSERT command to fail with an application error, or the application might stop responding (hang) while other programs remain responsive. The symptoms of the problem can vary, but may include messages similar to:

Application <Executable file name> has performed an illegal operation and will be shut down. Fatal Exception 0xC0000005

Symptoms
In SQL Server 2005, you create a linked server that is linked to the local server itself. This configuration is also known as a loopback linked server. Then, you create a stored procedure that contains a statement that resembles the following statement:

INSERT <LocalTable> EXEC <LinkedServer>.<ProcedureName>When you run the stored procedure, you receive the following error message:

Msg 3910, Level 16, State 2, Line 1
Transaction context in use by another session.Note This problem does not occur in Microsoft SQL Server 2000.
Resolution
This problem occurs because of a design change in SQL Server 2005.
