Hi all,

I have a question regarding clause 2.3.2 Error conditions.
In sub-clause B) it says,

B) At the TRACKING state (while the "track timer" has not expired)
      receiving a CONNECT message from that Peer ID with invalid swarm
      actions (section 5.1) is considered an error condition.  The
      Tracker responds with error code Forbidden (described in
      section 4.3), stops the "track timer", deletes the registration,
      transitions to TERMINATE state for that Peer ID and the SM is

If a peer that has already joined multiple overlay networks(swarms) tries to join invalid swarm,
it looks like that the registration should be removed according to above sentence.

Am I understanding right?

I think that such situation probably happen often, since a user may mistype or session may be removed by owner.
How about don’t going TERMINATE state but just send error message for the transaction.
