Can you explain this one? You register for datapath leave and did not see it?

The switch is disconnected and then removed from the list of active
sockets (hopefully sending a datapath leave in the process). Then,
when you send the packet with this datapath id, NOX cannot from a
socket with this datapath ('cos it's removed). Hence, the error.
