Thanks for the reply Boaz. Sorry for the late reply, was away for a while. 
We run ES ver 1.2.2 and use the zulu openJDK from azul.

So I'm going to get you the mappings in another post, but I think the 
cluster ended up becoming corrupt from an incident we saw about 1 1/2 weeks 
ago. I started another discussion about it 
here: 
https://groups.google.com/forum/?fromgroups=#!topic/elasticsearch/JwM0Gz9YO5M

I'm thinking the continuous updating of mappings (which caused the internal 
DOS on the cluster) possibly had a sequence where it lead to a bad update 
of the state file.

The state file for that incident was pretty big (70MB+), I'm not sure if 
you want that. I can probably get a scoped down version of the mappings we 
had after the  incident.

Thanks,
-Josh
