It's happening because it might have crossed the retry connection limit. After number of retries it destroy the TCP connection and become idle. So for it increase the number of retries and it would be better if you increase the gap between connection retry.

Use below options:

retryMiliSeconds {Number, default:5000}, number of milliseconds between retries.
numberOfRetries {Number, default:5}, number of retries off connection.

Solution:

MongoClient.connect("mongodb://localhost:27017/integration_test_?", {
    db: {
      native_parser: false,
retryMiliSeconds: 100000,
numberOfRetries: 100
    },
    server: {
      socketOptions: {
        connectTimeoutMS: 500
      }
    }
  }, callback)
