I agree with Gail that this should be posted in a new thread, but based on what you posted it soulds like your database is using the bulk_logged or full recovery model and you have no transaction log backups running against the database. The only way to clear the t-log is to run transaction log backups or switch your database to the simple recovery model.
Sorry, didn't think a new thread was needed - didn't see the point of creating a new post for the same type of question... but, will definitely do should this occur again.
Lynn, as an FYI the DB is in FULL mode with TLog backups running every 15 minutes (successfully) - I was just confused that the log_reuse_wait_desc
still said LOG_BACKUP, even when nothing was running...
I'll open a new thread
