Hi Experts, I have a requirement which leads me to return more than two arrays to the subroutine which is called from the main subroutine. a) array @nodelist is holding all the server names on which i am running some actions using the script. b) array @errorlist is holding all the server names on which actions failed. From getting the number of elements in @errorlist i need to finally spit in the logs the total number of servers which failed out of total. Below is the code snippet which i am using to return 2 arrays. But somehow this is not working. Instead of passing the array itself i am passing the reference to the array which is also giving some memory errors. I am not sure why. Any ideas are highly appreciated. 
sub main {
my $path = 'E:/scripts/OutageNodes/';
require $path.'omwNodeDetails.pm';
open_log($path.'maintenanceMode_');
my $mode=get_mode();
my ($nodelist,$errorlist) = get_node($path.'serverlist.txt');

  if( $mode eq 'enable'){
        enable_unplanned_outage(@nodes);
                     }
  elsif($mode eq 'disable'){
        disable_unplanned_outage(@nodes);
               }
  else {
       printLog("Error invalid Mode $mode");
    }
    
    
    
# clear serverlist
printLog ("Truncating serverlist");
open( SRV,'>',$path.'serverlist.txt') 
      or die "Can't open SRV '$path.serverlist': $!";
close SRV;
close_log();

printLog("there were ".scalar @$errorlist." errors in serverlist");

}




sub get_node {

  my ($infile) = @_;
  my @nodelist  = ();
  my @errorlist = ();
    
  ##checks if the file exists and pulls the info out
  if (-e $infile){
    open INFILE, '<', $infile or die "Could not open $infile : $!";
    print_log("Scanning $infile");
    while (my $node = <INFILE>){
      chomp($node);
      my ($hostname) = split /\./, $node;
      my $fqdn = getNodeAttributes($hostname,'PrimaryNodeName');
      if (length($fqdn) < 1) { 
        print_log("No value returned from WMI, node ($node) doesn't ex
+ists in OMW.");
        push @errorlist,$node;
      } else { 
        print_log("$node => $hostname => $fqdn");
        push @nodelist,$fqdn;
      }
    }                                     
    close INFILE;
  }
  else {
    print_log("ERROR Cannot open $infile");
  }  

  return (\@nodelist,\@errorlist);
}
