Swoole\Redis\Server 返回MAP或者SET时报错，有遇到同样问题的同学么？怎么解决的？

swoole版本：1.9.6，客户端：phpredis，版本：3.1.1
错误信息：WARNING swManager_check_exit_status: worker#7 abnormal exit, status=0, signal=11 
服务器端代码：
```php
$server->setHandler('sAdd', function ($fd, $data) use ($server) {
    if (count($data) < 2) {
        return Server::format(Server::ERROR, "ERR wrong number of arguments for 'sAdd' command");
    }

$key = $data[0];
    if (!isset($server->data[$key]))
    {
        $server->data[$key] = array();
    }
    
    $count = 0;
    $dcount = count($data);
    for($i = 1; $i < $dcount; $i++)
    {
        $value = $data[$i];
        if (isset($server->data[$key][$value])) {
            continue;
        }
        
        $server->data[$key][$value] = 1;
        ++ $count;
    }

return Server::format(Server::INT, $count);
});
$server->setHandler('sMembers', function ($fd, $data) use ($server) {
    if (count($data) < 1) {
        return Server::format(Server::ERROR, "ERR wrong number of arguments for 'sMembers' command");
    }

$key = $data[0];
    if (!isset($server->data[$key])) {
        return Server::format(Server::NIL);
    }

return Server::format(Server::SET, array_keys($server->data[$key]));
});
```
客户端访问时，无数据可以正常返回false，有数据时报错：
```php
$redis = new Redis();
$redis->connect('127.0.0.1', 9507);
$redis->set('a', '123');
var_dump($redis->get('a'));
//string(3) "123"
var_dump($redis->del('a'));
//int(1)
var_dump($redis->get('a'));
//bool(false)
var_dump($redis->sAdd('a', 1, 2, 3, 4));
//int(4)
var_dump($redis->sMembers('a'));
//等待10几秒后报错
//PHP Warning:  Uncaught RedisException: read error on connection in php shell code:1
//Stack trace:
//#0 php shell code(1): Redis->sMembers('a')
//#1 {main}
//  thrown in php shell code on line 1
```

$key = $data[0];
