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
Try:
[memcached]
memcached.sess_lock_wait_min = 100;
memcached.sess_lock_wait_max = 1000;
memcached.sess_lock_retries = 30;
Do you use the same version of Memcached with CI2 and CI4?
yes I am using same version of memcached 1.6.6
