Sorry but which is the server, phoenix?

No further traffic is generated for this connection?
For a problem like this, you really need to dump on both sides to get the full picture. Otherwise it's difficult to tell why we have a gap after 234561792 which is never filled in by dione.
BTW any reason why you appear to have SACK off?
