java invoked oom-killer #22788
Elasticsearch version: 5.1.2 (and 2.4.4)
Plugins installed: 
JVM version: Oracle JDK 1.8.0_121 (and OpenJDK 1.8.0_111)
OS version: Ubuntu 16.04
Description of the problem including expected versus actual behavior:
Steps to reproduce:
Provide logs (if relevant):
I only get the following Kernel Error:
There is also Logstash running on this node, but the error also happens if it is stopped.
Same issue here.
It's probably related to the kernel.
We are reverting to 4.4.0-57-generic.
Just to confirm, we had similar issue in our production environment running ES 2.4.4 with Ubuntu-16 with kernel 4.4.0-59. Linux was sacrificing the cluster nodes randomly due to OOM.
