here's a longer log from the server, with sequences, flags, etc:

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?

Cheers,
