Su un server Windows 2012 R2 cluster con SQL Server 2014 Enterprise.
Ho appena aggiornato un'istanza da 2014 SP1 CU4 a 2016 RTM e ora viene visualizzato questo errore quando si tenta di avviare SQL Server Agent.

L'agente si avvia e viene eseguito per circa 30 secondi, quindi muore con l'errore sopra riportato. Qualcuno ha riscontrato questo problema? E sai come risolverlo?
