Hello @Pruline, merci d'avoir remonté ce bug dans un ticket !

Je vois des lignes d'erreur qui concernent OSMDownloader, c'est un plugin que tu utilises pour charger des données ?

Sinon, le "_ArrayMemoryError" me fait penser au ticket #43. As-tu essayé de configurer le nombre de jobs en parallèle comme décrit ici : #45 ?
