Azure Service Bus and EPI
Some exceptions is expected under short intervals, it's a cloud service so there is a lot of retry logic to deal with rescaling and reassigning happening in Azure Service Bus and other network related resources. Maybe we should not log exceptions that automatically is fixed by a retry within shorter intervals.
I would not expect longer periods of errors unless Microsoft has stability issues posted on their status page, that could indicate that an error happening that the EPiServer provider does not deal with correctly or a bug in the code.
If you have support for Azure there is always the possibility to use the tracking token in the exception to get an answer of the error from Microsoft.

I'm currently working on a deployment in Azure.
The broadcast of events is working, I can see the expected number of subscribers is registered (w3wp instances) on the topic configured and that messages is posted and retrieved… but…
I also encounter a lot of exceptions thrown from in calls made by EPI-->Service Bus trying to read messages , that is à EPiServer.Azure.Events.AzureEventProvider.ReceiveMessage…
This exception-behavior makes me a little pensive if this is an expected behavior, a bug in EPI or if specific configuration setting is missing (not explained in the deployment scenario)?
