{push @array, $row;}

I'd suppose you're simply running out of memory, because you're collecting all the data in the @array.  2 GB memory usage for representing 100 MB file contents in an array (of arrays) structure isn't that unusual.

Do you actually need to hold the entire data in memory, or might there perhaps be a way to process things sequentially?
