What versions of Elasticsearch and Logstash are you using? ---

That's weird, those should be compatible. Are you sure all your ES nodes are running 1.6? Can you gist or pastebin the log messages before and after that first log message (like the full exception trace). It's hard to tell from a single isolated log line exactly what's going on here. ---
