hi every1, I write this snippet so as to do priority for everyone queue, but what's wrong with join? Actually in POSIX C-lang I use pthread_join, I've read docs about perl thread, but still complicated why happening so funky things with that? Also for input values into testing log I do echo 4-2-67-1 >> tst.log. 
use threads;
 
my %queue;
 
file_watchdog();
 
exit 1;
 
sub file_watchdog {
open(TRAP, '<tst.log') or die "can't open file_watchdog!";
while (1) {
select(undef,undef,undef,0.2);
my $a .= <TRAP>;
if(length($a) gt 0 ){
checker($a);
}
}
close (TRAP);
}
 
sub  checker {
my ($y) = @_;
if($y =~ /(\d+)\-(\d+)\-(\d+)\-(\d+)/){
        my $ip =$1;
        my $idx= $2;
        my $time = $3;
        my $th = $4;
my $thr_h;
        $queue{$ip}{$idx}{TICK} = $time;
        if($time < 5  ){
        my $wait = 7-$time;
        $queue{$ip}{$idx}{WAIT} = $wait;
        print "IP:$ip IDX:$idx TIME:$time TH:$th WAIT:$wait \n";
        if($th){ #Thread 2 terminated abnormally: Not a CODE reference
+ at thread.pl line 34, <TRAP> line 2.
        $thr_h->{$ip} = threads->create(\&wait_q($ip,$idx)); #->join()
+;
        }else{
        wait_q($ip,$idx);
        }
        }else{
        if ($thr_h->{$ip}->is_joinable()) {#Can't call method "is_join
+able" on an undefined value at thread.pl line 40, <TRAP> line 3.
        $thr_h->{$ip}->join();
        }
        print "do_connection() IP:$ip\n";
        }
 
        }
        }
 
sub wait_q {
my $ip = shift;
my $idx = shift;
        sleep( $queue{$ip}{$idx}{WAIT} );
        oid_checker($ip);
}
