Can't shrink Log file - "An invalid Floating point operation occurred. (Microsoft SQL Server, Error: 3623)" When selecting the Transaction Log file from the dropdown on the Shrink Files screen in SSMS, I get the following error:


  Failed to retrieve data for this request.  (Microsoft.SqlServer.Management.Sdk.Sfc)  Additional information:  An invalid Floating point operation occurred. (Microsoft SQL Server, Error: 3623)


It is happening on the same database on 2 different servers (restored from a SQL 2008 R2 Enterprise Ed. server to a SQL 2016 Standard Edition server nightly).  There are older copies spawned of the same database on QA and Dev from dates 2 months ago, and they do not experience the issue, so it is something that happened recently.  

I have tried:


DBCC CHECKDB - no errors
Took DB offline, deleted transaction log, recreated t-log using T-SQL. - No effect on error message
Detached DB, Reattached - No effect on error message
Set DB to FULL recovery mode (was previously on SIMPLE), allowed users to generate a good amount of transactions successfully. - No effect on error message
Set DB back to SIMPLE recovery mode. - No effect on error message
Attempted DBCC SHRINKFILE (&lt;database_name&gt;_log, 1).  - No effect on error message.  However, running this did generate the following message:


  Msg 8985, Level 16, State 1, Line 24
  Could not locate file '&lt;database_name&gt;_log' for database '&lt;database_name&gt;' in sys.database_files. The file either does not exist, or was dropped.



... Which made me decide to go do a select over sys.database_files and see if anything looked out of place.
It looks normal to me... look and see if you see anything that looks abnormal:

UPDATE  Since now I'm able to shrink the log using T-SQL  (DBCC SHRINKFILE (_log,...) ), I'm lowering the urgency of a fix.  However, I would still like to know if anyone has a fix for the original error, when shrinking using the GUI in SSMS.
You should update your question with the full @@version of your server.

You mentioned only that you use SQL Server 2008 R2, if you are only on SP2 this hotfix is for you:  Cumulative update package 8 for SQL Server 2008 R2 Service Pack 2

Among the issues it fixes, there is yours:



But I recommend you to patch your server to SP3.
