Elastic errors in logs

Elastic Stack Elasticsearch

Hi Team ,

I am seeing the below error in my Elastic cluster logs.

[ WARN] 2016-03-31 09:53:22,953 org.elasticsearch.discovery.zen.publish - [node3] timed out waiting for all nodes to process published state [5826] (timeout [30s], pending nodes: [[node2][naG4xE1qTv25eeJljtVKrw][node2][inet[/x.x.x.x:9301]]{local=false, master=true}])

Can anyone help me out why we are getting these type of warnings

It means that nodes in your cluster have timed out and are likely dropping out of the cluster.

Why is hard to say, could be GC, could be networking issues.
