Davido's got your memory fault, but that's pretty inconsistent code formatting, and poor error reporting on the opens. (Remember, $! is your friend, and it never hurts to print the name of the file that failed to open in your error message)

Where you have: `open(my $LOG,">>LOG_file") or die("Cannot open");` [download] Change it to: `open(my $LOG,">>LOG_file") or die("Cannot open: $!");` [download] This will display more information as to why you couldn't open the file. See open, perlvar and since you're new to perl: perlintro http://learn.perl.org http://perldoc.perl.org The tutorials section of this site	[reply] [d/l] [select]

Better change it to: `my $filename = 'LOG_file'; open(my $LOG, '>>', $filename) or die("ERROR: Cannot open file '$filen +ame' for appending: $!");` [download] McA	[reply] [d/l]

use autodie; try a demo `$ perl -e " use autodie; open my($fh), qw[< noexist ]; " Can't open 'noexist' for reading: 'No such file or directory' at -e li +ne 1` [download] the reason it can't open comes from $!	[reply] [d/l]
