Is there another way rather than choosing smaller region ?
Yes, wait for sp 0.9-12, which is "on its way to CRAN", where zerodist
should work without a large memory footpr

Most probably you have duplicate points in your observations.
You may try to use zerodist() to find them, or remove.duplicates() to

r-project.org -> CRAN -> Select Mirror -> Task Views -> Spatial.
