Hi, We've been observing some strange exceptions in our cluster. Some of the instances are throwing up exceptions like the ones below. We are running a 6 node cluster with ES 1.3.0. Data is being pushed to ES via a storm cluster. Any clues as to what these exceptions mean and how to overcome?

Looks like something nuked that file directory out from under the elasticsearch process. ---

These are production systems with very limited access. Any other reasons? Its probably worth mentioning - its a cluster of 6 c3.xlarge instances with data being stored on EBS with 1000 provisioned IOPs. ---

This issue has been reproduced repeatedly. Would appreciate any kind of help or pointers. ---

Anyone from elastic team? How can I get any inputs on this? ---
