Hi, I tried what you said about Thread::Pool, and all the threads get started correctly but once I get to the 'if statement' that kills the threads, the foreach loop, get stuck in a infinte loops. I pasted some of my code in here, with a dummy sub function I created to test the pools. Any idea why the 'if(@result = $pool->result_dontwait($_))' statement never hits true?? -Otter 
my %hosts=();
my $counter=0;
my $global=0;
my $pool=();
my @result=();
my %ids=();
$pool = Thread::Pool->new(
{
    do => sub {\&Temp_function(@_);},
    workers => 10,     # default: 1
});


%hosts = &Telnet_host();
foreach (keys %hosts)
{
    $ids{$_}=$pool->job($_, $hosts{$_} );
}
while (keys %ids)
{
    foreach (keys %ids)
    {
        if (@result = $pool->result_dontwait($_))
        {
            print $ids{$_} . "\n";
            delete ($ids{$_});
        }
    }
    print "Items still to do: " . $pool->todo . "\n";
}


##--END FUNCTION CALLs--

{
    my ($ip,$mac)= @_;
    print $mac . "\n";
    return $mac;
}
