> Occasionally one sees erroneous protocol traces such as illustrated by the 
> following:
> {noformat}
> [apache.qpid.client.AMQConnectionDelegate_8_0] Connecting to 
> broker:tcp://localhost:10002?connectdelay='500'&retries='0'
> [transport.network.io.IoNetworkTransport] SO_RCVBUF : 65535
> [transport.network.io.IoNetworkTransport] SO_SNDBUF : 65535
> [transport.network.io.IoNetworkTransport] TCP_NODELAY : true
> [qpid.client.state.StateWaiter] New StateWaiter :AMQState: id = 4 name: 
> CONNECTION_OPEN:[AMQState: id = 4 name: CONNECTION_OPEN, AMQState: id = 6 
> name: CONNECTION_CLOSED]
> [qpid.protocol] SEND: 
> [org.apache.qpid.client.protocol.AMQProtocolHandler@501fdcfb] AMQP1109
> [apache.qpid.client.AMQConnection] Connection 3 now connected from 
> /127.0.0.1:50631 to localhost/127.0.0.1:10002
> [apache.qpid.client.AMQConnection] Are we connected:true
> [apache.qpid.client.AMQConnection] Connected with ProtocolHandler Version:0-9
> [apache.qpid.client.AMQConnectionDelegate_8_0] Write channel open frame for 
> channel id 
>                                                      ^^^^^^^^^^^^
> # What on earth         
> {noformat}
> The issue stems from a prior connection attempt which has reached the 
> connection open stage, but then (for some reason) closed.
> We can rectify this issue by using a new StateManager for each connection 
> attempt.
