Hey,

this is by far not enough information to help. Please take your time to describe your setup properly.

This is a debug message (are you logging on debug level by default? why so?). This message means that a HTTP was closed unexpectedly (maybe a network issue, impossible to tell).

Also, you should upgrade, Elasticsearch 1.3 is really old and you are missing a ton of bugfixes...
