ZooKeeper's initLimit Amount of time, in ticks see tickTimeto allow followers to connect and sync to a leader. It must be a completely separate physical server.
The consequence of using this default is that if started with a single server the ensemble will not be allowed to grow, and if started with more than one server it will not be allowed to shrink to contain fewer than two participants. ZooKeeper's maxClientCnxns Limits the number of concurrent connections at the socket level that a single client, identified by IP address, may make to a single member of the ZooKeeper ensemble.
