This can happen if there are no workers, if the workers have hit their high-water marks (unlikely, it is *very* high in Essex), or if they're blocked processing non-eventlet friendly tasks.  Assuming the network service is actually running, it seems most likely it might be stuck processing an eventlet unfriendly task.
