      I have this sample application running with a replica set:
      'use strict';

      const MongoClient = require('mongodb').MongoClient;

return MongoClient.connect('mongodb://ip1:port1,ip2:port2,ip3:port3/dbName?replicaSet=testSet', function(err, db) {
    if (err) {
        return console.error('Err:', err);
    }

    setInterval(function() {
        console.log('Interval');

        return db.collection('tests').count({}, function(err, count) {
            if (err) {
                console.error('Err:', err);
            } else {
                console.log('Count:', count);
            }
        });
    }, 2000);
});
{

      When I block all the outgoing/incoming connections with a firewall, the Mongo client keeps all the pending outgoing requests in a buffer. Then, when I unblock the connections, nothing happens. It seems the client does not reconnect and the application stays frozen.

      Note: Sometimes there is a reconnection but it's unpredictable.
