En attendant une meilleur réponse,

Bonjour,

en attendant une vrai réponse, vous pourriez trouver quelle source génère ce message en cherchant quel fichier contient ce message.

Réglages / Système / Configuration
Onglet tout à droite : >_OS/DB
2ème bouton rouge : Administration système
Dans le champ de saisie tapez :
grep -rn --include=*.php 'file created in the system' /var/www/html/plugins

Grep est un outil de recherche de chaine de caractères. Cette commande recherche « file created in the system » dans les fichier *.php sous le répertoires « /var/www/html/plugins » et ses sous-répertoires et renvoie le nom de fichier avec le numéro de ligne où il trouve ça.

merci pour vos indications. j’ai passé les logs non plus en warning mais en debug et j’obtiens peutetre l’origine de ces entrées vu que c’est au même moment et trèèès souvent. je vais donc creuser dans cette direction. je clos

etc

Ce message d’erreur est lié à une mauvaise configuration de php dans l’installation jeedom. En effet, le upload_tmp_dir est défini à « /userdata », et cet emplacement n’a des droits d’écriture qu’en tant que root, pas en tant que www-data (qui est utilisé lors des appels http).
Du coup, on a ce message qui indique, lors d’un upload de fichier, que l’upload est redirigé vers le sys_temp_dir si défini (ce qui n’est pas le cas), ou vers le dossier temporaire défini sur l’OS lui-même.
En d’autres termes, à moins d’un fix du php.ini (ex. pour mettre une localisation dans /var/www/html/) ou des permissions par défaut pour www-data sur /userdata, on aura ce genre de message pour tout upload, quelque soit le plugin utilisé (voire le core).
Pas terrible…
En attendant, individuellement, vous pouvez faire l’une des corrections indiquées ci-dessus. A vos risques et péril en terme de sécurité bien sûr.
