nodejs connect mongo have memory leak

In node.js I use expressjs and when connect to mongodb, I have a trouble and I have no idea why it happens. I search about it but it's unclear.

(node) warning: possible EventEmitter memory leak detected. 11 reconnect listeners added. Use emitter.setMaxListeners() to increase limit.
