Those maxconn values are per frontend so if your backend is referenced by
two frontends you might end up with a limit of 2 x maxconn on the backend.
Hence it is recommended to set maxconn per server too to protect from
situation like this. So read about maxconn and even fullconn in the server
config and tuning guide for more details.
