Assistance technique

Merci Séverin pour ta réponse.

Effectivement, le module sub_course avait été mal désinstallé...je l'ai réinstallé, lancé le cron, puis désinstallé proprement. Les messages le concernant ne sont plus présents maintenant. Plus aucun message d'erreur mais toujours plus de 130 secondes, malgré que les process accumulés ne fasse pas ce temps...ce qui est surprenant est qu'il y ait un temps de plusieurs secondes supplémentaires entre chaque tache lancée, et je ne sais pas comment le réduire (16h03m03s tache se lance et prend 0.14 sec, puis il faut attendre 16h34m23s pour que la suivante se lance, soit 20 sec entre les deux ??

Pour répondre à ta question, je n'ai modifié aucune ligne de lancement du cron...il est lancé par une tâche planifiée sur mon Centos 

"/usr/bin/php /var/www/vhosts/foad.swimmingpole.fr/moodle/admin/cli/cron.php >/dev/null" en tant que "style cron"

PS: souvent le message suivant lorsque je le lance à la main:

!!! L'opération s'est interrompue dans l'attente d'un verrouillage. !!!

tu me confirmes bien que c'est alors qu'il est en train de se faire et que deux session de cron ne peuvent avoir lieu ensemble ?

En te remerciant !
