Event hubs silent disconnect and no reconnect

Expected Behavior

Messages are getting processed without losing connection.

Current Behavior

After a couple of days our connection drops and event hubs is not reconnecting. We are still seeing that telemetry data is being sent by the library.

Possible Solution

When the connection drops reconnect. If reconnect doesn’t work try again in 1 minute and keep doing this indefinitely until connection is possible.

Steps to Reproduce (for bugs)

Not reproducible. But when your connection is open long enough it will drop.

@yiliuTo thank you! My first tests were looking positive. We are deploying them now to our staging cluster. If that is stable they will go to UAT where we have lots of messages. I will keep you updated here.
