I´d make a backup and try

akonadictl fsck

then, as I believe, that would clear out unreferenced entries in there or move 
them to lost+found where you can delete them. It seems that by belief is 
backed by a post from Einar in forums:

Can you try first with an "akonadictl fsck"? This should wipe references to 
things that are no longer stored in Akonadi. Notice that it will return 
immediately - things will be done in the background.

If the database is huge, you can also try

akonadictl vacuum

I don´t know whether this will do anything with the cached files as akonadictl 
seems to be heavily underdocumented:

martin@merkaba:~> LANG=C man akonadictl
No manual entry for akonadictl
See 'man 7 undocumented' for help when manual pages are not available.

(rarely seen on a Debian machine as it is policy to have a manpage for each 
executable)

I have had issues with it as well, as I have more than 500000+ files in there 
at work with one huge IMAP account.

I am not aware of any other way to influence it. Also note: If you make that 
clean start and delete anything in ~/.local/share/akonadi/file_db_data/ as to 
my understanding there may still be files that Akonadi caches only there. As 
for new mails, I think, Akonadi may cache them there until storing it at their 
final location. But well, you have IMAP, so then this is no issue, but with 
locally stored mails aka POP3 it may be.

Ciao,
