Connection request: [route:
{}->http://966b.http.dal05.cdn.softlayer.net:80][total kept alive: 0; route
allocated: 1 of 1; total allocated: 1 of 10]
Note that the last log of “Connection request” reports that “route allocated: 1
of 1”.
It probably means that the connection was not released when the channel was
shut down.
>From the client perspective, the consumer’s onByteReceived is never called
>after this point.
