There is no error response for this, because it isn't an error. It is
quite legal to establish multiple subscriptions for the same event.
While in some cases this might be redundant and silly, it is difficult
or impossible for the notifier to distinguish the useful cases from the
silly ones.

Hi
Which is the appropriate 4xx message that can be used to inform user of
an existing subscription?
Consider the following use case: User A sends a subscribe message with a
particular event and gets subscribed to the service. Now at a later
point of time the user is not sure if he has subscribed for a particular
service or not. So he might send subscribe again. So is there a way to
inform the user that the subscription for that service for the user
already exists?
Thanks
Regards
Ranjit
