      In cluster mode, the driver monitors all hosts - actives, passives and arbiters.

      In fact it is not necessary to monitor the arbiters since the driver never connects to them.

       

      In our infra, the arbiters are firewalled and so we always get these messages:

      The solution I think is to remove addNewHosts(description.getArbiters()) from MultiServerCluster.ensureServers()
