the problem is  in Tk listbox appear only one time  a data stream
why ??, if anyone have some idea is welcome  thanks at all

this is a my code (perl 5 strawbaerry in windows 10 64bit )

use threads;
use threads::shared;
use Perl::Tidy;
use Tk;
use Tk::LabFrame;
use Tk::ROText;
use strict;
use IO::Socket::INET;

my $x:shared=1;
my $data :shared;

my @workerThreads;
my @otherThreads;
push @workerThreads , threads->create (\&threadSub1) for (1..10);
push @otherThreads , threads->create (\&threadSub2) ;
$_->join() for @workerThreads ;
$_->join() for @otherThreads ;

print("$x\n");



sub threadSub2 {
my $mw = MainWindow->new ;
$mw->geometry( "600x600" );
my $lbox = $mw->Listbox(-height =>500, -width =>500)->pack();


$lbox->insert('end', $data );

MainLoop;


}

sub threadSub1 {
    # auto-flush on socket
    $| = 1;

# creating a listening socket
my $socket = new IO::Socket::INET (
    LocalHost => '127.0.0.1',
    LocalPort => '23456',
    Proto => 'tcp',
    Listen => 5,
    Reuse => 1
);
die "cannot create socket $!\n" unless $socket;
print "server waiting for client connection on port 23456 \n";

while(1)
{
    # waiting for a new client connection
    my $client_socket = $socket->accept();

    # get information about a newly connected client
    my $client_address = $client_socket->peerhost();
    my $client_port = $client_socket->peerport();
    print "connection from $client_address:$client_port\n";

    # read up to 1024 characters from the connected client
    #my $data = "";
    $client_socket->recv($data, 1024);
    print "received data: $data\n";

   my  @data_array = split(/;/,$data);
    foreach (@data_array) {
        return "$_\n";
      print "$_\n";
    }

    # write response data to the connected client
    $data = "ok";
    $client_socket->send($data);

    # notify client that response has been sent
    shutdown($client_socket, 1);
}

$socket->close();
}
