Hey nikita after some experimenting today i found the issue is actually caused by my log-courier installation and the ticket that i have raised on the logstash github repo. The also notified log courier devs aswell I found by moving back to lumberjack fixed my issues and i am now running elasticsearch 2.0 with logstash 2 and kibana 4.2 ---

Yeah, I got to know too that it's the courier plugin.. I was just wondering which was the version where courier plugin didn't cause this issue.. ---
