I dont know if it's folder permissions (nothing changed there since the upgrade) or something else. There's no

Steps to reproduce

1) Add Whitelist to config.xml

https://developer.adobe.com/commerce/php/tutorials/backend/modify-image-library-permissions/

  <system>
        <media_storage_configuration>
            <allowed_resources>
                <media_gallery_image_folders>
                    <banners_image_folder>banners</banners_image_folder>
                    <brandlogos_image_folder>brandlogos</brandlogos_image_folder>
                </media_gallery_image_folders>
            </allowed_resources>
        </media_storage_configuration>
    </system>

2) Login to Admin 3) Go to: Content -> Media Gallery

Expected result

Directory list is generated and no error thrown

Actual result

Directory list is not generated, error is thrown and Admin user logged out.

Additional information

Not sure whats going on, both my local machine and DEV Server with same settings do not have this issue.

Although, the directory tree does take at least 5 seconds to show up.

My server admin said there was not enough memory assigned - he added more and now this:

Its timing out via Cloudflare (100 second limit?)

[pmonosolo]

Looks like whatever the task that runs when it looks through folders runs for too long and just bricks the Media Gallery.

Is there some list generation happening or does this run every time the Media Gallery is opened?

We have a lot of images in our folders, so I assume its related.

Hello @pmonosolo,

Thanks for the report and collaboration!

We have tried to reproduce the issue in the Magento 2.4-develop branch but the issue is not reproducible for us. In order to reproduce the issue we have made a custom module which is attached as follows: Magz.zip

We are not getting any error in the below page:

Please let us know if we have missed anything.

Hello @engcom-Hotel

it looks like its related to this issue from 2.4.1: https://github.com/magento/magento2/issues/30596

Same issue, many images, process overloads PHP RAM limit and stalls.

I have tested switching back to Old Gallery Style and that is working - so at least we have some workaround.

The number of images it stalls on is - 5780. Please try more as I dont know the exact process it's using to go through the images (does it go through /catalog/product folders?)

@engcom-Hotel Can you please test with a large number of images in the /media folder?

[pmonosolo]

I dont know if it will help, the files that were throwing out of memory error were these:

[07-Oct-2022 22:26:54 UTC] PHP Fatal error: Allowed memory size of 792723456 bytes exhausted (tried to allocate 8192 bytes) in /home/userhome/public_html/vendor/magento/framework/Filesystem/Driver/File.php on line 1042

[07-Oct-2022 22:26:54 UTC] PHP Fatal error: Allowed memory size of 792723456 bytes exhausted (tried to allocate 692224 bytes) in /home/userhome/public_html/vendor/magento/framework/Session/SessionManager.php on line 133

I'm having issues replicating the same issue on my local DEV machine with the same amount of files.

I dont know if it's environment related, missing PHP extensions or something else.

The server was migrated recently to PHP8.1 so I assume maybe there's something missing.

[engcom-Hotel]

Hello @pmonosolo,

Thanks for the reply!

As you said, your production server is just migrated with PHP 8.1. So I suggest you check your memory_limit configuration in the PHP.ini file. Meanwhile, we are trying to reproduce the issue with a large number of files.

Thanks

[pmonosolo]

@engcom-Hotel

Our memory limit is up already to 8GB.

There are similar threads on this topic: https://github.com/magento/magento2/pull/35404

[engcom-Hotel]

Hello @pmonosolo,

We have tried this issue with ~8002 images in a folder but still, we are unable to reproduce the issue. I am attaching the screenshot for reference:

For us also the memory_limit is set to 8GB and we are using PHP8.1.

Let us know in case we have missed anything.

Thanks

@engcom-Hotel Sorry I ran out of steam - the 2.4.5 upgrade took everything out of me...lol.

I'll need to re-approach this in the new year or if somebody in https://github.com/magento/magento2/issues/30596 will pick this up.
