SQL Server doesn't start after you configure the tempdb database to use a very small log file

Symptoms

Consider the following scenario:
  • You use Microsoft SQL Server 2012, 2014, or 2016.
  • You use the ALTER DATABASE … MODIFY FILE … statement to configure the tempdb database to use a new log file.
  • You specify the new log file size to be smaller than 248 KB.
  • You stop and then restart the instance of SQL Server to apply the change.

In this scenario, the instance of SQL Server does not start. Additionally, error messages that resemble the following are logged to the SQL Server error log:
Error: 9004, Severity: 21, State: 1.
An error occurred while processing the log for database 'tempdb'.  If possible, restore from backup. If a backup is not available, it might be necessary to rebuild the log.


Error: 945, Severity: 14, State: 2.
Database 'tempdb' cannot be opened due to inaccessible files or insufficient memory or disk space.  See the SQL Server errorlog for details.
