Google indexing a big .PDF file, can this cause any problems?

[waziwazo]

I have posted a very large .PDF file on my website (15 MB)
Cant make it smaller, this is a whole book, about 260 pages that i put on my website an that peoples can download.

I noticed that Google spider downloaded it when it was spidering my site.

Can this cause any problems for my website with Google spider?
