Tengo un problema intermitente que aparece solo en un servidor y hace que todas las páginas MVC no se carguen con el error "Ya se ha agregado un elemento con la misma clave".

Al reiniciar el grupo de aplicaciones se soluciona el problema, pero hasta entonces, al cargar cualquier página mvc, se produce la siguiente excepción:

Custom event details: 

Como se mencionó, es cada acción de MVC que lanza este error hasta que se reinicia el grupo de aplicaciones, y el error parece estar ocurriendo enSystem.Web.WebPages.Scope.WebConfigScopeDictionary.TryGetValue(Object key, Object& value)

¿Alguien ha visto este problema antes? Solo sucede en este servidor, en cualquiera de los grupos de aplicaciones en el servidor (no limitado a este) y un reinicio del grupo de aplicaciones lo ordena.

Cualquier ayuda muy apreciada.

Aclamaciones,

Mateo

EDITAR DE NUEVO

Ok, ya que parece que no hay una respuesta fácil a la pregunta anterior, quizás haya una respuesta a esta: ¿Puedo configurar IIS para reciclar automáticamente el grupo de aplicaciones después de encontrar un número específico de errores dentro de un período de tiempo específico? Sé que podría habilitar la protección rápida contra fallas, pero eso no es lo que busco, ya que entonces tendría que reiniciar manualmente el grupo de aplicaciones. Como solución (lea: piratear ...) Quiero arreglarlo para que se reinicie si se produce una carga de errores seguidos. ¿Es eso posible en su lugar?

Una edición más

Ok, este error ocurrió en otro servidor esta mañana también, así que parece que no es solo la configuración del servidor lo que lo está causando. Tal vez sea algo en mi código, pero estoy perplejo en cuanto a cómo diagnosticarlo, ya que no puedo replicarlo y no puedo depurarlo ... Parece que tengo algo más de investigación que hacer.
