写了个定时器，日志却在不停的增长

代码基本上是仿照文档写的。

$room_config=array();
$task = new Worker();
$task->count = 1;
$task->onWorkerStart = function($task)
{
    global $room_config;
    ReloadRoomConfig();
    //定时检测房间设置
    $check_room_interval = 30;
    Timer::add($check_room_interval, function() use (&$room_config)
    {
        info('ReLoad Room Setting ...');
        ReloadRoomConfig();
    });

    //聊天机器人
    Timer::add(1,function() use (&$room_config)
    {
        //处理随机聊天业务
    });
};

Worker::runAll();

调试模式很好，但是用-d模式日志一直在增长，不知道为什么。

#tail -f workman.log

2018-06-19 01:04:19 pid:30444 Worker process terminated

2018-06-19 01:04:19 pid:30450 Worker process terminated
2018-06-19 01:04:19 pid:30451 Worker process terminated
不断循环...
