If it is working with a smaller import I do not believe it will be the database.
It maybe due to a single contact having a special character which is knocking the data a column over, this would be difficult to narrow down.
but halfing the spreadsheet maybe another way to try and narrow down further.

You could also try saving the spreadsheet at TAB delimited and try importing that. It tends to solve problems where a rouge comma moves data and therefore stops the import.
