> We recently saw an issue where network issues between slaves and the NN
> caused ESTABLISHED TCP connections to pile up and leak on the NN side. It
> looks like the RST packets were getting dropped, which meant that the client
> thought the connections were closed, while they hung open forever on the
> server.
> Setting the SO_KEEPALIVE option on our sockets would prevent this kind of
> leak from going unchecked.
