We recently upgraded our MongoDB Node.js driver as our MongoDB server was upgraded to 3.2. Mongodb 2.0.34 --> 2.2.24 Mongodb-core 1.2.0 --> 2.1.8. Our MongoDB is a 3 node replicaset with self signed ssl certs. Since upgrading the Node.js drivers our application now exits with an uncaught exception if one of the secondary nodes goes offline. When using a connection string with multiple servers in a replicaset, Ping() does not detect if one of the MongoDB instances go offline, it will not throw an exception. Only if I call Reconnect() will the driver detect that one of the instances are offline and throw an exception when calling Ping().
