Kettle loses rows

I have this simple transformation:

from_access_to_mysql.jpg

I would like to convert a MS Access DB to a MySQL one.

In the "table out" step I have set 1000 as "commit size" and I have selected "use batch update for inserts". The Access DB has 500.000 records, but I lose 3% of them during the conversion. Sometimes, I get more than 500.000 rows in the MySQL db.

I've tryed changing the commit size and disabling the ""use batch update for inserts" option, but I have the same problem.

Someone may help me?

Thanks in advance.
