重复给TCP服务器发送消息导致worker线程无响应，是否为存在内存泄漏的问题

客户端代码：
<?php
swoole_timer_tick(10, function () use ($client) {
           $client->send($data);
});
这样重复给swoole tcp服务器发送消息，每次发送840次左右，服务器就无响应了。必须重启才能接收新的请求。会不会是内存泄漏导致的？

服务器端代码：

```php
/**

 * User: Administrator
 * Date: 2016/1/8
 * Time: 17:06
 */
namespace service;
class Server 
{
    protected $_logFile = 'server.log';
    protected $_host = "0.0.0.0";
    protected $_port = 9990;
    protected $_serverConfig = [];
    /**
     * @var \swoole_server
     */
    protected $_server;
    /**
     * @var \swoole_process
     */
    protected $_process;

/**
     * @var \swoole_atomic
     */
    protected $_taskNum;
    protected $_defaultServerConfig = [
        'worker_num' => 8,   //工作进程数量
        'task_worker_num' => 2,
        'daemonize' => false, //是否作为守护进程
        'open_length_check' => true, //打开包长检测
        'package_max_length' => 8192000, //最大的请求包长度,8M
        'package_length_type' => 'N', //长度的类型，参见PHP的pack函数
        'package_length_offset' => 0,   //第N个字节是包长度的值
        'package_body_offset' => 4,   //从第几个字节计算长度
    ];

public function onConnect($server, $fd)
    {
        $this->log("Client:Connect. client id: " . $fd);
    }

public function onReceive(\swoole_server $server, $fd, $from_id, $data)
    {
        
		// 检查task数
		if($this->_taskNum->get()>100){
			return;
		}
		
		$bool = $server->task($data);
		$this->_taskNum->add(1);
        if (!$bool) {
            $this->log('Task ERR!');
        } else {
            $this->log('Task Suc!');
        }
    }

public function onClose($server, $fd)
    {
        $this->log("Client: Close.");
    }

public function onTask(\swoole_server $server, $task_id, $from_id, $taskData)
    {
        $this->log('Task Start num=' . $this->_taskNum->get());
        //业务逻辑处理
        $server->finish(1);
    }

public function onFinish(\swoole_server $server, $task_id, $data)
    {
        $this->log("Task#$task_id finished, data_len=" . strlen($data));
        $this->_taskNum->sub(1);
        $this->log('Task Finish num=' . $this->_taskNum->get());
    }

public function serve()
    {
        $server = new \swoole_server($this->_host, $this->_port);
        $this->_server = $server;
        $this->_taskNum = new \swoole_atomic(0);
        $server->set($this->_serverConfig);
        $server->on('connect', [$this, 'onConnect']);
        $server->on('receive', [$this, 'onReceive']);
        $server->on('close', [$this, 'onClose']);
        $server->on('task', [$this, 'onTask']);
        $server->on('finish', [$this, 'onFinish']);
        $server->start();
    }
}
```
我试过：1.7.1与1.8.2，都是同样的问题。
