Das Laden einer MVC-Seite schlägt mit dem Fehler "Ein Element mit demselben Schlüssel wurde bereits hinzugefügt." Fehl.
Ich habe ein zeitweise auftretendes Problem, das nur auf einem Server auftritt und dazu führt, dass alle MVC-Seiten nicht mit der Fehlermeldung "Ein Element mit demselben Schlüssel wurde bereits hinzugefügt" geladen werden.
Das Neustarten des Anwendungspools behebt das Problem, aber bis dahin löst das Laden einer beliebigen MVC-Seite die folgende Ausnahme aus:

Custom event details:
Wie bereits erwähnt, wird dieser Fehler von jeder MVC-Aktion ausgelöst, bis der App-Pool neu gestartet wird und der Fehler anscheinend in auftrittSystem.Web.WebPages.Scope.WebConfigScopeDictionary.TryGetValue(Object key, Object& value)
Hat jemand dieses Problem schon einmal gesehen? Dies geschieht nur auf diesem Server, in einem der App-Pools auf dem Server (nicht auf diesen beschränkt), und ein Neustart des App-Pools sortiert ihn.
Jede Hilfe sehr geschätzt.
Prost,
Matthew

Set compilation debug="true" to insert debugging symbols (.pdb information)

WIEDER BEARBEITEN:
Ok, da es anscheinend keine einfache Antwort auf die obige Frage gibt, gibt es möglicherweise eine Antwort auf diese Frage: Kann ich IIS so konfigurieren, dass der App-Pool automatisch wiederverwendet wird, nachdem innerhalb eines bestimmten Zeitraums eine bestimmte Anzahl von Fehlern aufgetreten ist? Ich weiß, dass ich einen schnellen Fehlerschutz aktivieren könnte, aber das ist nicht mein Ziel, da ich dann den App-Pool manuell neu starten müsste. Als Workaround (read: hack ...) möchte ich das Problem beheben, damit es sich von selbst neu startet, wenn mehrere Fehler hintereinander auftreten. Ist das stattdessen machbar?
EIN MEHR BEARBEITEN
Okay, dieser Fehler ist heute Morgen auch auf einem anderen Server aufgetreten. Es scheint also nicht nur die Serverkonfiguration zu sein, die ihn verursacht. Vielleicht ist es etwas in meinem Code, aber ich bin ratlos darüber, wie ich es diagnostizieren soll, da ich es nicht replizieren und nicht darin debuggen kann ... Scheint, als ob ich noch weitere Nachforschungen anstellen muss.
