WebSocket ws://*******:9501 connection failed: Invalid frame header

错误日志：ERROR	zm_deactivate_swoole (ERROR 9003): worker process is terminated by exit()/die().
出现这种错误我现在都是直接kill 掉占9501 端口的进程，重启服务器脚本，暂时可以推送数据了，过几个小时，又出现了上面的错误，
服务器代码
include_once  PROJECT_PATH . '/lib/box/redis.php';
//链接redis
$redis=new MY_redisCluster();
$flag=$redis->connect(array('host'=>'127.0.0.1','port'=>6378));

	$server->set(array(

		}

		if(!empty($frame)){
			foreach($server->connections as $fd)
			{
				//广播
				$server->push($fd, $frame->data);
			}		
		} 
	});
	$server->on('Request', function(swoole_http_request $request,swoole_http_response $response) { 
		global $server;  
		global $redis; 
		//获取推送的数据
		$request=(array)($request);

			}
			$response->end($data);
		}
	});
