-> I was executing DBCC SHRINKFILE as an one time operation on a huge data file to move its data into 4 additional data files using below command,

USE [Financedb]
GO

DBCC SHRINKFILE (N'Finance_Data' , EMPTYFILE)
GO

-> I received below error when executing above command,

Msg 1119, Level 16, State 1, Line 20
Removing IAM page (3:5940460) failed because someone else is using the object that this IAM page belongs to.

-> I executed DBCC CHECKDB and there were no errors,

DBCC results for ‘Financedb‘.
.
.
CHECKDB found 0 allocation errors and 0 consistency errors in database ‘Financedb‘.
DBCC execution completed. If DBCC printed error messages, contact your system administrator.

-> This is not a corruption issue. I restarted SQL Services and executed below command and it ran through.

USE [Financedb]
GO
DBCC SHRINKFILE (N'Finance_Data' , EMPTYFILE)
GO

Msg 2555, Level 16, State 1, Line 20
Cannot move all contents of file “Finance_Data” to other places to complete the emptyfile operation.
DBCC execution completed. If DBCC printed error messages, contact your system administrator.

-> Above message is due to the fact that System objects cannot be moved.

Thank You,
Vivek Janakiraman
