Sorry for re-opening it. The close=false is deliberate after the discussion.

>                 Key: DISPATCH-506
>                 URL: https://issues.apache.org/jira/browse/DISPATCH-506
>             Project: Qpid Dispatch
>          Issue Type: Bug
>    Affects Versions: 0.6.1

>             Fix For: 0.8.0
> Hi,
> I got the following scenario.
> A router with a link routing configured on address "my_queue".
> A broker hosting "my_queue".
> A Python receiver connected to that queue through the link routing provided by the router.
> If I kill the receiver, so the TCP connection between client and router is dropped, the
client (of course) doesn't send a detach to the broker for the link but the router is in charge
to do that.
> What happens is that this detach message doesn't contain an "error" field in order to
distinguish between a clean detach from the client or a detach sent by router due to client
"brute" disconnection.
> Following the trace I have :
> [0x16e07f0]:  <- EOS
> [0x16e07f0]:  -> EOS
> Closed
> Unexpected poll events: 0020 on
> [0x16cf470]:0 -> @detach(22) [handle=0, closed=true]
> [0x16cf470]:0 <- @detach(22) [handle=0, closed=true]
> [0x16cf470]:0 -> @end(23) []
> [0x16cf470]:0 <- @end(23) []
> I think that it could make sense that router sends a detach with "error" when something
like that happens.
> The current is a bug or a behavior ?
> Thanks,
> Paolo.
