Ralentissement de la connexion via OTB depuis hier

Bonjour,
Depuis hier, nous rencontrons des ralentissements au niveau de notre connexion Internet via OTB, ainsi qu'une dégradation de la qualité des appels en VOIP.
Quand je regarde dans le log de l'OTB, et j'ai ces informations, que je n'avais pas avant :

J'ai rebooté l'OTB cette nuit, je n'avais plus ces erreurs. Mais c'est revenu aujourd'hui.
Nous n'avons pas apporté de changement à l'installation ...
Si besoin, je peux communiquer le Device_ID en MP.
Merci pour vos lumières.
