Where's located your code?
You might want to check those things:
autocron: this is an Osclass-feature that runs Cron without the need to configure the crontab. Head to Settings > General and check if autocron is checked. It makes a new HTTP request for it, so your code might be running twice.
ajax: you might have some ajax query in one of your enabled plugins or theme that makes a request on each loading and run your code twice.
From what I see, you might want to use the 'init' hook to be sure it gets executed once. Something like this:
osc_add_hook('init', function () {
$session = Session::newInstance();
$userId = $session->_get('userid');
$itemId = $session->_get('itemid');
// Do something.
});
Also, try to take a look at DAO in Osclass and plugin development, here's a tutorial that will get you through Osclass plugin development and the use of DAO.
