Temporary table - Error recovery failure (9001) (1 reply)

I have made temporary table like this:

CREATE TEMPORARY TABLE temp1 (towkod varchar(20), townaz varchar(40), wartnetto DECIMAL(9,2), wartzysk DECIMAL(9,2), ilotow DECIMAL(9,2)) ENGINE = InnoDB

and then insert 6 milions rows:

INSERT INTO temp1 (towkod, townaz, wartnetto, wartzysk, ilotow)
VALUES ('aaa', 'name aaa, 1.1, 2.2, 3.3)

but after insert 3 milions rows apear error:

Unrecoverable error 9001, Error recovery failure

what is wrong?
