Hi All,

I have a problem with my cluster. I have 2 nodes. They are on the same physical machine. But one of them disconnected. I don't understand why it is disconnected while they are on the same physical machine. DO you have any idea about this problem? By the way I use ElasticSearch 0.19.0.

Thanks..

Is there anything interesting in the logs?

You _do_ know that 0.19.0 is insanely old, right?

Hi Magnus,
