If you are getting a database is full warning that means you have to make sure you have made a full backup of the DB so that it will then truncate the size of the log file so it does not grow so large. 

See this article on how to resolve this issue. Database is full or Log file Growing too Large

Or if you see a message like this.  Your database is full due to space allocated to growth of database files or available space on the hard drive it is stored on. Or if you use SQL Express edition you have reached the 10 gig primary file group limitation. See link that your IT department can use to resolve this issue. Thank you.
