session_write_close(): Failed to write session data using user defined save handler.

[weierophinney]

Occasionally,we get the following not yet reproducible warning:

WARN: session_write_close(): Failed to write session data using user defined save handler. (session.save_path: ) {"errno":2,"file":"/var/www/html/vendor/zendframework/zend-session/src/SessionManager.php","line":229}

This is how we initialize the session:

// Load config
$config = $serviceManager->get('Config');

// Initialize session
$sessionConfig = new SessionConfig();
$sessionConfig->setOptions($config['session']);

$sessionTableGateway = new TableGateway('session', $serviceManager->get('Zend\Db\Adapter\Adapter'));
$saveHandler = new DbTableGateway($sessionTableGateway, new DbTableGatewayOptions());

$sessionManager = new SessionManager($sessionConfig, null, $saveHandler);
$sessionManager->setName($config['session']['name']);

$sessionManager->start();

Container::setDefaultManager($sessionManager);

I am facing a similar issue since upgrading to PHP 7.1 . I should note though, that we are using a VERY old version of Zend Framework: 1.10.

I do notice though that your session.save_path seems to be empty?
(session.save_path: )
There should probably be something there like /var/lib/php/session

Yes, I am facing exactly the same issue here. I am using also the session-db, i don't know why he reproduces this error pointing to something like if was saved on local disk.

I'm also experienced the same issue but my particularity is that the session save handler want well to store user id (after logging) but doesn't want to store data session cart to sessiondb

🤔 I'm facing the exact same issue when I use Zend\Cache\Storage\Adapter\BlackHole::class as save handler

I also occasionally experience the error (E_WARNING):

session_write_close(): Failed to write session data using user defined save handler. 
(session.save_path: /var/lib/php/sessions)

in src/SessionManager.php on line 234.

What is interesting is that I am using Zend\Session\SaveHandler\DbTableGateway as a SaveHandler.

The session with the session ID included in the error log is not stored in the database.

The error happens sporadically and is not reproducible.

I am using zend-session 2.9.1.

Yes unfortunately we have the same error here..

[FabianKoestring]

I think we have the exact same problem. We use our own SaveHandler and getting this exception ....

Is this issue still occuring with laminas-session versions > 2.9.1?
Did anybody resolve this issue with an upgrade of the laminas-session Version?
I am still facing this problem, I am using laminas-session 2.8.7, with php7.3-fpm.

[tyrsson]

Im still getting the same random error with laminas-session 2.13.0, DbTableGateway SaveHandler, php 8.1.1, windows 10

[romantaranenko]

@StefanGerl laminas/laminas-session version 2.12.1 with PHP 8.1.13 and i have it.

Errors like these seem unrelated:

Cannot update a readonly entity

I'm closing here: please consider opening a new issue with logs presenting exactly:

• which session savehandler was used
• how it was configured
• which method calls on the savehandler have been performed (you may need to decorate it)
