使用gatewayworker 和redis消息订阅造成的多进程阻塞

public static function onWebSocketConnect($client_id, $data)
{
    $token=$data;
    $encryptedData = base64_decode($token);
    $arr=json_decode($encryptedData,true);
    $codeArr=explode(',',strtoupper($arr));
        global $redis;
        $_SESSION = $client_id;
        $redis->subscribe($codeArr,function ($instance, $channelName, $message){
            if(!empty($message)){
              var_dump($message);
            }
        });
}
