SQL Server Floating Point Exception

Tony Wu 1 Reputation point

When run a simple query against a full text search table, I got a floating point error. See below sql statement and error message.

SELECT TOP 10 * FROM FREETEXTTABLE (dbo.FreeTextTable, (F1, F2, F3, Fr), 'Keyword here') AS ft

Error Message
Msg 3628, Level 16, State 1, Line 1
The Database Engine received a floating point exception from the operating system while processing a user request. Try the transaction again. If the problem persists, contact your system administrator.

My SQL Server version is:

Microsoft SQL Server 2019 (RTM-CU10) (KB5001090) - 15.0.4123.1 (X64)

    Please try to apply the latest Cumulative Update package (CU11) for your SQL Server 2019 instance first.

    Do you have a repro? That is, a simple script that builds a database, populates a table, creates a full-text index and then runs a query that produces this error?

    I would not really expect that it is simple to produce such a repro, as it is likely to be dependent on your data and maybe a few more circumstances.

    As Cris says, first apply CU11 just to see if this may fix the issue.

    But if that does not work out, I would recommend that you open a support case. Assuming that it is a bug in the product, the support case should be of no cost for you at the end.

    There is a small risk that it is due to corruption of some sort, so you could run DBCC CHECKDB on the database before you open a support case. You could also work on a copy of the database where you drop and recreate the full-text index.
