It's actually in zmq.
Terminated pipe writer gets a "activate" command. But load balancer
doesn't decrement active pipe count in terminate() call.
55 void zmq::lb_t::terminate ()
56 {
57 zmq_assert (!terminating);
58 terminating = true;
59
60 sink->register_term_acks (pipes.size ());
61 for (pipes_t::size_type i = 0; i != pipes.size (); i++)
62 pipes [i]->terminate ();
63 }
