PHP가 세션 저장 경로를 redis로 설정한 후 PHP의 fpm이 충돌했습니다.

<code><?php
namespace Session;

use SessionHandlerInterface;

class MySession implements SessionHandlerInterface {
    private $redis;

    private function connect() {
        if(!$this->redis) {
            $cfg = [
                'scheme' => env('REDIS_SCHEME', 'tcp'),
                'host' => env('REDIS_HOST', '127.0.0.1'),
                'port' => env('REDIS_PORT', 6379)
            ];
            $this->redis = new \Predis\Client($cfg);
        }
    }

    /**
     * Close the session
     * @since 5.4.0
     */
    public function close()
    {
        $this->redis->quit();
        return true;
    }

    /**
     * Destroy a session
     * @since 5.4.0
     */
    public function destroy($session_id)
    {
        $this->connect();
        return $this->redis->del($session_id);
    }

    /**
     * Cleanup old sessions
     * @since 5.4.0
     */
    public function gc($maxlifetime)
    {
        return true;
    }

    /**
     * Initialize session
     * @since 5.4.0
     */
    public function open($save_path, $session_id)
    {
        return true;
    }

    /**
     * Read session data
     * @since 5.4.0
     */
    public function read($session_id)
    {
        $this->connect();
        return $this->redis->get($session_id);
    }

    /**
     * Write session data
     * @since 5.4.0
     */
    public function write($session_id, $session_data)
    {
        $this->connect();
        $expire  =  configure('Ymf.Account.expire');
        if(is_int($expire) && $expire > 0) {
            $result = $this->redis->setex($session_id, $expire, $session_data);
            $re = $result ? 'true' : 'false';
        }else{
            $result = $this->redis->set($session_id, $session_data);
            $re = $result ? 'true' : 'false';
        }
        return $re;
    }
}</code>

이것은 내 코드입니다. 무엇이 잘못되었는지 어떻게 디버그할 수 있나요
