Why am I getting "print () on a private file descriptor with a bad file descriptor" in my Perl script?

I have a tcp server in perl (version 5.0 version 8 subversion 0) that use this routine to enter the file.

sub logger {
        return if ($LOGFILE eq "") ;
        my ($idt, $str) = @_ ;
        unless( defined($str) ) {
                $str = $idt ;
                $idt = '' ;
        }
        my ($s,$m,$h,$J,$M,$A) = localtime(time()) ;
        if(!open(OUT,">>$LOGFILE"))
        {
                warn "logger:error open [$LOGFILE]:[$!]\n";
                return;
        }
        if (!printf OUT "%4.4d/%2.2d/%2.2d %2.2d:%2.2d:%2.2d %s %s -> %s\n",
                      $A+1900, $M+1, $J, $h, $m, $s, $idt, $HOSTNAME, $str)
        {
                warn "logger:error print [$LOGFILE]:[$!]\n";
                return;
        }
        if (!close(OUT))
        {
                warn "logger:error close [$LOGFILE]:[$!]\n";
                return;
        }
}

Therefore, this log file has a simultaneous entry. Exceptionally , I have this error in STDERR:

printf () on closed filehandle

logger: error print [/my/path/logFile.LOG.BIZ:[Bad File Descriptor]

no errors when opening!

How can I solve this problem?

OUT - . , , Log4perl, , $OUT:

sub logger {
    $LOGFILE or return;
    my ($idt, $str) = @_ ;

    unless( defined($str) ) {
        $str = $idt ;
        $idt = '' ;
    }

    my ($s,$m,$h,$J,$M,$A) = localtime(time()) ;

    my $OUT;

    unless (open $OUT, '>>', $LOGFILE) {
        warn "logger:error open [$LOGFILE]:[$!]\n";
        return;
    }

    unless (printf $OUT 
        "%4.4d/%2.2d/%2.2d %2.2d:%2.2d:%2.2d %s %s -> %s\n",
        $A+1900, $M+1, $J, $h, $m, $s, $idt, $HOSTNAME, $str
    ) {
        warn "logger:error print [$LOGFILE]:[$!]\n";
        return;
    }

    unless (close $OUT) {
        warn "logger:error close [$LOGFILE]:[$!]\n";
        return;
    }

    return 1;
}
