Mongoose disconnects/reconnects every 30 seconds

We are using nodejs and mongoose on our production server. The mongo logfiles are full with connects/disconnects. They all happens every 30 seconds. 

Wed Jan 15 10:08:52.280 [initandlisten] connection accepted from 10.3.138.16:50946 #1089677 (137 connections now open)
Wed Jan 15 10:09:22.291 [conn1089677] end connection 10.3.138.16:50946 (140 connections now open)

Does anyone have a clue about this?

This is what the fine manual states:

A note about keepAlive

For long running applictions it is often prudent to enable keepAlive. Without it, after some period of time you may start to see "connection closed" errors for what seems like no reason. If so, after reading this, you may decide to enable keepAlive:

options.server.socketOptions = options.replset.socketOptions = { keepAlive: 1 }; 
mongoose.connect(uri, options);
