If I'm not mistaken, you are dealing with a total of: > 414180 * 1515 * 4 / 1024^2 [1] 2393.657
or close to 2.4GB, for a single copy of the (combined) array. Unless you're on a 64-bit OS running on hardware with sufficient physical RAM, that's not likely to work so well. Also, I believe you should close() the connections before rm() them.
