### What happened?

I have configured session store as memcached, it was working fine in PHP 7.1 with codeIgniter 2,

After upgrading PHP 7.1 to 8.2 and codeIgniter 2 to 4 I am getting an error on multiple async ajax call

```
session_start(): Unable to clear session lock record
in SYSTEMPATH/Session/Session.php on line 928.
1 [internal function]: CodeIgniter\Debug\Exceptions->errorHandler()
2 SYSTEMPATH/Session/Session.php(928): session_start()
3 SYSTEMPATH/Session/Session.php(250): CodeIgniter\Session\Session->startSession()
4 SYSTEMPATH/Config/Services.php(674): CodeIgniter\Session\Session->start()
5 SYSTEMPATH/Config/BaseService.php(252): CodeIgniter\Config\Services::session()
6 SYSTEMPATH/Config/BaseService.php(193): CodeIgniter\Config\BaseService::__callStatic()
7 SYSTEMPATH/Config/Services.php(641): CodeIgniter\Config\BaseService::getSharedInstance()
8 SYSTEMPATH/Config/BaseService.php(252): CodeIgniter\Config\Services::session()
9 SYSTEMPATH/Common.php(988): CodeIgniter\Config\BaseService::__callStatic()
```

codeIgniter official website also suggests to use session_write_close() for resolving this issue. But this did not work for ajax concurrent call.

### Steps to Reproduce

When I am calling multiple sync ajax than getting error

### Expected Output

Getting Json Response

### Anything else?

_No response_

Bắt đầu tại SYSTEMPATH/Session/Session.php dòng 928 và lần theo đường dẫn của startSession() gọi session_start(). Tái hiện lỗi với Memcached trong nhiều yêu cầu AJAX đồng thời trên PHP 8.2 và so sánh hành vi với phản hồi JSON dự kiến. Vấn đề được giải quyết khi các yêu cầu đồng thời không còn báo lỗi session lock-record.
