It's a message from Xen. It only gets printed if the network device
driver's transmit function returned an error. This should never happen
(if the driver isn't ready to accept packets there is a way to signal
that).
  
Maybe it's a driver or hardware bug. Maybe Xen is running low on
memory (unlikely).
