I have a recurring issue with nsq_to_nsq where it will deadlock. It appears a network transport issue on the publisher connection propagates into blocking consumer connections and they stall and get kicked from their respective nsqd instances and it does not reconnect.

This is a placeholder and i'll add more information as investigation continues.

The trigger appears to be the following failure on the producer connection. (And in case it turns out to be important, i'll mention that we are using --mode=hostpool)
