wp_generate_attachment_metadata memory issue (Advanced) (1 post)

    I have a script that imports lots of large images from an external source into WordPress. I've run in to a memory issue that I am trying to debug. When triggered manually, the image upload works but the script dies at this point

    $attach_data = wp_generate_attachment_metadata( $attach_id, $filename );
    wp_update_attachment_metadata( $attach_id,  $attach_data );

    So it seems that WordPress dies when trying to generate thumbnails. I am not able to upload the file manually via Media Library either. There I get

    Fatal error: Allowed memory size exhausted in .../wp-includes/media.php

    I was thinking it's php memory limit causing it but the script does not fail when triggered by wp_cron.

    I have tried setting WP_MEMORY_LIMIT and WP_MAX_MEMORY_LIMIT but neither seems to have an effect.

    Any ideas?
    Thanks in advance!
