Hi All, I upgraded elasticsearch servers from 1.4.2 to 1.5.2 recently and got noticed that kibana 3.1.2 working fine with es 1.5.2 added following property. http.cors.enabled: true http.cors.allow-origin: "/.\*/" ``` so no issues after upgrading server but recently my es nodes got shutdown automatically because of OOM issues.from that point onwards kibana 3.1.2 is not working.showing connection failed exception even though we have cors added to es.yml file I restarted server but exception not solving please address my issue how can we solve this? ``` Thanks, phani ---

What do your ES logs show, what about your nginx/apache logs (whatever is serving up KB)? ---
