Service WCF occupé (CommunicationException)

Bonjour,

J'ai un souci sur mon application Silverlight. J'ai un Service WCF côté Serveur qui plante quand je fais trop d'appels à ce service.

Il me retourne cette Exception :

{System.ServiceModel.CommunicationException: Le serveur distant a retourné une erreur*: NotFound. ---> System.Net.WebException: Le serveur distant a retourné une erreur*: NotFound. ---> System.Net.WebException: Le serveur distant a retourné une erreur*: NotFound.
