[Option] /DumpOnError [Description] 
(Optional) Creates the debug dump files, .mdmp and .tmp, when any error occurs while the package is running. By default, Integration Services stores the debug dump files in the folder, :\Program Files\Microsoft SQL Server\100\Shared\ErrorDumps folder. Note Debug dump files may contain sensitive information. Use an access control list (ACL) to restrict access to the files, or copy the files to a folder with restricted access. For example, before you send your debug files to Microsoft support services, we recommended that you remove any sensitive or confidential information. To apply this option to all packages that the dtexec utility runs, add a DumpOnError REG_DWORD value to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\100\SSIS\Setup\DtsPath registry key. The value of the DumpOnError REG_DWORD value determines whether the /DumpOnError option needs to be used with the dtexec utility: A non-zero data value indicates that the system will create debug dump files when any error occurs, regardless of whether you use the /DumpOnError option with the dtexec utility. A zero data value indicates that the system will not create the debug dump files unless you use the /DumpOnError option with the dtexec utility.
