Hello, we are experimenting some problems with GC configuration of
ElasticSearch,
we have elasticsearch 0.20.2 running in java 6.0.32 with 9 node with 32 gb
and 16 gb assigned to the elastic, in this cluster, we have one index with
20 shard and 2 replicas, we have around 15k of request per minute.
After a few hours, at least one node is expelled of the cluster and the
logs that we see are:

I don't know how we can resolve this problem, we try diferents
configurations in the in the elasticsearch.in.sh but the problem persist.
would be great if someone could help with this.
