Is the table a pre-existing empty table, or is it being
created on the fly by the import ?  In the latter case,
does your table have a primary key, or other index -
as this could explain why you are seeing two large
rollback segments. (Although 200M of table plus an
index shouldn't take anything like a gigabyte of undo).

Which error message are you getting ?
