There should be, yes. It'll be in your akonadi dir, which should be
located under one of either XDG_DATA_HOME or XDG_CONFIG_HOME, IDR which.
There should be two logs, one for the current akonadi session, one for
the previous, if there were errors (not if there were none). IIRC one of
the akonadi-test/config tools has a test that will give you the status of
these logs, etc.
At least that's how it was as of kdepim 4.7.0 or so...

I'm guessing that if you check the actual filesystem, you'll find most of
the messages safely stored in maildir. The akonadi database doesn't
actually store the messages, only indexes them. It's that index that's
probably corrupt, and if you find the the actual dir location, you may be
able to (delete if necessary and...) recreate a new akonadi resource out
of it, thus allowing a reindex.
However, it was exactly that sort of games with my mail that I had had
enough of when I switched to claws-mail. Claws may have single-threading
and responsiveness issues, but it has yet to barf all over my mail and
try to lose bits of it, forcing me to play hide and seek with mail that
DID "just work" with kmail, until they akonadified it, as akonadi was
doing.
