Using a local instance of Parsoid and MCS, when querying MCS for the article Portail:Accueil/Bandeaux :
http://localhost:6927/fr.vikidia.org/v1/page/mobile-sections/Portail%3AAccueil%2FBandeaux
Parsoid times out and exits:

I think this must be a bug, because the page does not seem large in and of itself: https://fr.vikidia.org/wiki/Portail:Accueil/Bandeaux
