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 ?
