websocket一直报warning,无法关闭，业务却正常？

### 问题描述
log_file 每隔一13秒连续3秒输出这个

### php和swoole版本，代码运行平台等相关信息
PHP 7.2.24 (cli) (built: Mar  5 2020 16:58:04) ( NTS )
swoole-src-4.4.7

### 相关代码
```php
请将代码黏贴至此处（请勿用截图）
$ws->set([
    "daemonize"=>true,
    'log_level' => SWOOLE_LOG_ERROR,
    'trace_flags' => SWOOLE_TRACE_SERVER,
    "log_file"=> '/home/wwwroot/dengji/swoole.log',
    "max_conn"			=> 512,
    'open_cpu_affinity'	=> 0,//用CPU亲和设置(在全异步非阻塞是可启用)
    'worker_num'		=> 4,//和CPU核心一致
    'heartbeat_check_interval '=>11,//和客户端的心跳检测，用于用户下线
    'heartbeat_idle_time'=>23
]);

开了个定时器

if(!$server->taskworker&&$id==1){
        _LOG($server->taskworker);
        _LOG("开启定时器");
        $server->tick(15000,function () use ($server){
//            $closeFdArr = $server->heartbeat(true);
                $closeFdArr = $server->heartbeat(false);
                 _LOG("TICK:当前待关闭人数数:".count($closeFdArr)."ids".join(",",$closeFdArr));
                foreach($closeFdArr as $fd) {
                    $closeRs = $server->close($fd);
                }
        });
        _LOG("定时器开启结束");
    }

### 你期待的结果是什么？实际看到的错误信息又是什么？
