Hello,

Bug reported at ¹ and reproducible, while trying to download the PDF version of ². Maybe the same as bug 40468.

«
Une erreur est survenue sur le serveur de rendu : RuntimeError: command failed with returncode 9: ['mw-render', '-w', 'rl', '-c', 'cache/09/09c542e0b954a798/collection.zip', '-o', 'cache/09/09c542e0b954a798/output.rl', '--status', 'qserve://localhost:14311/09c542e0b954a798:render-rl', '--template-blacklist', 'MediaWiki:PDF Template Blacklist', '--template-exclusion-category', "Exclure lors de l'impression", '--print-template-prefix', 'Imprimer', '--print-template-pattern', '$1/Imprimer', '--language', 'fr'] Last Output: 5379001% rendering 85.1229646266% <snip> 91.6855699045% rendering in function system, file /home/pp/local/bin/nslave.py, line 64
»

If this is because the book is too big to render, would it be possible to improve the error message?

Thanks in advance, best regards,
