I wrote a script 3 years ago to merge and sort 2 logfiles which has worked perfectly until this week.

Unfortunately now each of the 2 logfiles are nearing 1 gb in size and when I try to combine the files into an array (to sort later), the script crashes below (with no error). I have run the script with smaller logfiles and it combines and sorts correctly.

Any ideas on a work around.

The code where I try to combine the files is below.

sub GroupRows {
    my ($LogName) = @_;
    open LOGA, "< $LogName" or die "Cannot open $LogName\n$!\n";
    while (! eof(LOGA)) {
            chomp($line_a = <LOGA>);
            if (($line_a =~ /^\#/) 
                        { 
                           undef $line_a;
               next;
            } else {
                 push(@LogVals, $line_a);
            }
    }
    close(LOGA);
}
