That is what I mean.
When using --single-transaction the dump will start with
BEGIN TRANSACTION. So MySQL will try to use very large
transactions when importing the data into NDB. So if the
--single-transaction is removed the import will happen in
many small transactions instead which will avoid these
problems.

But obviously setting max_allowed_packet smaller also
somehow decreases the transaction size. Not sure exactly how
this happens.
