I am running a 10 nodes es cluster, and everything is ok. yesterday I add 8 new nodes to the cluster, the new nodes work well at beginning, but after several hours later, all the new nodes disconnected from the cluster, and the http request to new nodes will get stuck, while the old nodes still work well.
The es process in new nodes still exist but not ouput any log(include gc log). cannot be kill by sign 15. But when I use strace or jstack operate on es process, it back to noraml again, I tried this 4 times, and 4 times the process back to normal!!!
