in thread Show error "Out of Mermory"!!

Saving to a file might not solve the problem, you haven't said whether you disabled buffering or not, you haven't shown that either. In Perl you got line-buffering and block-buffering, saving to files employs block buffering since print and write operations are involved hence sometimes you need to enforce a buffer flush every time a filehandle is written to in case you are afraid that memory issues would come-up.

print OUT "$line\n";
autoflush OUT 1;

This link can be useful for you to learn more about buffering and for pseudo hashes, a quick googling around the place can give you an indication; Pseudo-hashes deprecated, pseudo hashes.. Perl is a lovable language, just be committed to it and do what it takes to get there.
