"Outof Memory Error loading big SPSS file"

Hi there,

I am having a problem while loading a big SPSS file in RapidMiner. (pasted below)
The file is about 420 MB (over 1 million lines and 70 columns)

My question: what memory does the error refer to? RAM memory?

Thanks a lot

Braulio

Here is the error:
