HTTP ERROR 500 / Duplicate entry for key 'sessions_pkey'

cendocu · April 28, 2026, 12:54pm

Hi,

When using the original SessionDAO.php and SessionManager.php files (without the patches), the HTTP 500 error appears again.

The last plugin we enabled was the DOAJ plugin, a little over a week before the issue started. It was working correctly—DOAJ successfully harvested all records from the FACES journal without any problems.

The mystery continues…

Could upgrading to version 3.5 be a possible solution? Time is passing, and the editorial teams of our journals are increasingly insisting on regaining access to the platform.

One of our concerns about upgrading to version 3.5 is the PKP Preservation Network plugin, which is not yet compatible with this new version.

Thanks

Hi, this is good. lets not apply those patches as I can not re-reproduce the issue locally, so can not confirm the validity of those patches . Those was a possible solution based on some theory .

in that case, does the HTTP 500 happening for everyone ? can you try to login from a different browser or from incognito/private mode and see if this works ?

cendocu · April 28, 2026, 2:42pm

Hi,

I’ve removed the patches. The website is down again.

We’ve already tried several things: logging in from different browsers, using incognito/private mode, and even testing from different computers, but the issue persists.

Same result for everyone.

Hi, I see that without that patches , the system is getting unavailable at a second load . lets do the following

re-add the patches that described at HTTP ERROR 500 / Duplicate entry for key 'sessions_pkey' - #10 by touhidur and add few debug loggings along with those patches as

          $this->userSession = $existingSession;                                                                                                                  
          return;                                                                                                                                                 
      }                                                                                                                                                           
                                                                                                                                                                  
      error_log("SESSION CREATE: id=" . session_id() . " new session"); // a logging here 
      // ... rest of method
  }

The update the SessionManager::write method as

/**
 * Save session data to database.
 */
public function write(string $sessionId, string $data): bool
{
    if ($this->userSession) {
        $this->userSession->setSessionData($data);

        error_log("SESSION WRITE: id={$sessionId} user_id=" . ($this->userSession->getUserId() ?? 'NULL') . " data_length=" . strlen($data));

        // If this request has no authenticated user, preserve any existing
        // user_id in the DB to prevent concurrent requests from overwriting
        // the login state set by another request (e.g., the login POST)
        if (!$this->userSession->getUserId()) {
            $existing = $this->sessionDao->getSession($sessionId);
            if ($existing?->getUserId()) {
                $this->userSession->setUserId((int) $existing->getUserId());
                error_log("SESSION WRITE: preserved user_id=" . $existing->getUserId() . " from DB for session {$sessionId}");
            }
        }

        $this->sessionDao->updateObject($this->userSession);
    }
    
    return true;
}

If the problem still persist, then from these logging we can get some details about where the problem is happening .

I’ve applied the new changes, but the issue still persists. The following errors are appearing in the Apache error log:

Hi, based on the last provided log, I don’t see a single log like SESSION WRITE ? was the patch SessionManager::write being applied ? if applied and provided logs are correct (without anything missing), then this points that for some reason, session not being written . Also logs points that for every request createSession being called which is also not right .

At this point, we need add more detailed log to see what is happening as truthfully, I am really out of ideas at this point .

we can update the following methods as

private function __construct()

  }

So need to update 3 methods in the SessionManager.php with more logging to see if we can figure out anything .

Hi, following your previous suggestion, I applied all the requested updates, specifically the last three you mentioned. The error log shows more types of error (SESSION CREATE, SESSION INIT, SESSION INSERT…).

What a nightmare, thanks!

Hi, the logs does not really adds up as expected . No calls to session write or session invalid . was all the patches applied ?

I am going to suggest something different

truncate the sessions table
clear the OPcache caches

if the logs does not appear as we expected , means something at infrastructure level has changed related to PHP’s session config .

Hi,

Yes, I’ve applied all the patches you suggested.

I also truncated the sessions table and cleared the OPcache, but the result in the error log remains the same:

When the issue first started (an early Sunday morning, with the “Duplicate entry for key ‘sessions_pkey’” error), we checked with the webmaster to confirm whether anything had been changed or updated on the web server. According to them, no modifications were made.

Thanks

Hi,
Since we couldn’t afford to wait any longer to resolve the login issue, we decided to proceed with an upgrade to version 3.5.0-4. The platform is now up and running.

This wasn’t our preferred option, but ensuring the continuity of the journals’ editorial operations had to take priority.

Thank you very much for your support, patience, and the time you dedicated to what felt like an almost endless journey.

Cristian

it seems the server is running Moodle at** /cv/ alongside OJS at /revistas/****. And Moodle is also having session problems (“Cannot find session record”).

If another PHP based application is running in same server and if both applications have session issues simultaneously, the problem is at the PHP/server configuration level, not in OJS code.

it feels like session.auto_start is set to 1/true/On in the PHP configuration . check the session auto_start config via command php -i | grep session.auto_start or something similar .

session.auto_start should be Off for OJS because OJS uses a custom session handler (SessionManager implements SessionHandlerInterface). If PHP auto-starts the session before session_set_save_handler() is called, the custom handler is never used , e.g. sessions seems to go to files instead of the database.

Hi,

Just to confirm, I checked this parameter and it is set correctly:

; Initialize session on request startup.
; https://php.net/session.auto-start
session.auto_start = 0

In any case, after upgrading to OJS 3.5 everything appears to be working properly. The upgrade wasn’t originally planned, but it ended up being the last resort to resolve the issue. Unfortunately, the root cause of the problem remains unknown at this point.

Thank you very much for all your help and support,

Cristian
