Hello,

While implementing the deployment API test plan, I've found the following test:

api-18:Create a System while subscribed with an invalid endpoint

Subscribe to a portal for creation events with a notification EPR that is invalid. There are the following types of invalid portal

Nonexistent URL (e.g. "http://notifications.example.org/epr1").
endpoint with no open connection (e.g. "http://localhost:8081/epr1"), assuming port 8081 is closed
404 URL (e.g. "http://deployment.sourceforge.net/example/epr1").

Assertions:

In all cases, the notification delivery failure is noted, the endpoint is no longer subscribed

Don't you think this behavior of simply unsubscribing the consumer in its first failure can result in bad unsubscriptions? I mean, the failure can be transient and only by a few seconds can make the consumer unreachable/invalid.
