Knowledge Base article:

Causes

The specified transaction log file has run out of free space.

Resolutions

To gain more space, you can free disk space on any disk drive containing the transaction log file for the related database. Freeing disk space allows the recovery system to enlarge the log file automatically. Or you can gain space by adding or enlarging a log file for the specified database.

You can free disk space on your local drive or on another disk drive. To free disk space on another drive:

Another solution is to add a log file to the specified database using the ADD FILE clause of the ALTER DATABASE statement. Or you can enlarge the log file using the MODIFY FILE clause of the ALTER DATABASE statement, specifying the SIZE and MAXSIZE syntax. Adding an additional log file allows the existing log to grow.
