After 30 mins of inactivity or so I start getting the below error when I try to insert into mongo, When I try again it starts to work. Error Below. I'm on Azure:

[INFO ] 2018-09-10T12:00:43,188 [http-nio-8080-exec-6] connection - Closed connection [connectionId{localValue:3, serverValue:26}] to XX.XX.XX.XX:27017 because there was a socket exception raised by this connection.

Here is how I initialize my mongo Template:

@Bean

    public MongoDbFactory mongoDbFactory() {

        String addresses = mongoUri.split(",");

        List<ServerAddress> servers = new ArrayList<>();

        for (String address : addresses) {

            String split = address.trim().split(":");

            servers.add(new ServerAddress(split[0].trim(), Integer.parseInt(split[1].trim())));

        }

        MongoClientOptions.Builder mongoOperations = MongoClientOptions.builder();

        mongoOperations.socketTimeout(1000 * 20); // I tried to increase the socket timeout to see if it helps but no help either

        mongoOperations.connectTimeout(1000 * 10);

        MongoClient mongoClient = new MongoClient(servers, MongoCredential.createCredential(userName, dbName, password.toCharArray()), mongoOperations.build());

        return new SimpleMongoDbFactory(mongoClient, dbName);

    }



    @Bean

    public MongoTemplate getMongoTemplate() {

        return new MongoTemplate(mongoDbFactory());

    }

My mongod version is 3.6.4 and I'm using the same version of java driver.
I tried to increase/decrease the tcp_keepalive_time setting as provided in the docs using
sudo sysctl -w net.ipv4.tcp_keepalive_time=120 but no help either.

ohk. so we found that the mongo java driver jar was older than the mongo server we were using which was causing this issue. make sure that the driver supports the version of mongo server.
