RIP problem w/hi-res file

I have a very high resolution PDF file that I created in Illustrator (19 megs). I've brought it to 2 different offset printing companies and they haven't been able to properly RIP the image from the PDF to make the plate. It has apparently been crippling their computers. In the Illustrator file that I created I used an extremely thin line stroke of .15 per line and there are hundreds of these lines all the same thickness in the 11in x 17in image. Does anyone have any ideas how it might be possible to RIP this file properly or how the file could be slightly altered to make it possible to RIP? Or is there some application that is the master RIPper for hi-res files like this?

Any Help Would Be Appreciated,

 

Which specific Fiery RIPs? (i.e. how powerful are the rips you are using)

 

yes export the file as a 600 dpi tiff from Illustrator, preserving overprints, works everytime.
