Hello.

At the end I solved the connecivities issues following the instructions in this link: [http://logz.io/blog/elasticsearch-cluster-disconnects/](http://logz.io/blog/elasticsearch-cluster-disconnects/)

To make a short recap: there is a bug in the ubuntu network driver that causes some random packets loss. In the syslog of the server I got messages like this:

`xen_netfront: xennet: skb rides the rocket: 19 slots`

The procedure to solve the problem is to disable the the Scatter / Gather ability in the network interface.

```
//To see if scatter-gather is ON on eth0:
ethtool -k eth0 |grep sca
//to set it to off:
ethtool -K eth0 sg off

```

@Christian_Dahlqvist: I will follow the recommendation regarding the allocated java heap, thank you for noting it.
