I noticed that the AWL database was getting rather large, so I used the check_whitelist script to remove the stale entries. While this seems to have removed a lot of entries from the database, it did not reduce the database size.
If you are using MySQL with the Innodb backend, removing entries will not always shrink the database's physical file.
