Zookeeper is just used for sharing the information which services are exported, it is not used for the actual remote conmmunicatio. If the zookeeper connection broke down, the remote services should get deregisted, not stop working. To me this sounds like e.g. a firewall is dropping the connection at some point, maybe due to inactivity. You should check the firewall settings/logs. I don't know how long it takes you to reproduce this, but you could test the theory by invoking a simple remote service every minute or so, to see if the periodic traffic prevents the firewall from dropping the connection.
