CUNY Academic Commons

I just tested a bit, and found some lag in the process, but no errors.

Can you be a bit more specific about exactly where you're seeing the "connection lost" error? Is it after selecting the file for upload (Add Media, then Browse)? Or is it after clicking Insert Into Post? Are you seeing the "connection lost" error in your browser console, or is your main browser window showing an error?

Thanks for the additional details, Luke. I'm still unable to reproduce exactly, but I do see some lag and some other odd behavior.

We've been seeing some odd tickets this morning that all point toward some changed server configs. I'm going to reach out to IT.

TLC has the Anthologize plugin activated.

The issue might be related to Anthologize using a PHP session and the session perhaps not being closed.

The following article about PHP sessions and WordPress explains the problem (read the "Exclusive Locks" section):

I experienced similar problems with long-hanging AJAX requests and PHP sessions with the WP Ajaxify Comments plugin.

I did the following to fix the problem in RBE:

But, we could probably use a more, general fix on the Commons.

Luke, I've added a hotfix to the Commons. Can you check and see if uploads are more reactive on TLC now?

Boone, this is what I added:

add_action( 'admin_init', function()  {
    if ( defined( 'DOING_AJAX' ) && true === DOING_AJAX && session_id() ) {
        session_write_close();
    }
}, 999 );

Sorry guys, just saw these updates. Deactivated Anthologize. Site is running pretty slow, and just uploaded an image to the media library... took over a minute for all the thumbnails to load. Was able to select the image without the disconnection. however.

See #7997. Let's try to work on that issue this summer, as I think it's the source of much of the mentioned slowness.
