hi,elasticserch

in my project ,we found elasticsearch a bug about agg search,  
when there were twice or more threads use java api aggregation to invoke es  
at the sametime,  
elasticsearch sometime cause error:None of the configured nodes were  
available,  
but one thread never apprear. we test many times,come to the conclusion .

1.our index data just Fifty million  
2.and agg search just like : select appid,count(id) from msprouterecord  
group by appid,  
3.our server is 32\*core 64g memory  
4.ulimit -v -m -l unlimited -n 204000  
5.elasticsearch 1.3.7

this bug no matter with server configuration and os environment ，always  
apprear.

please help us resolve quickly, thank you very much!
