Hi,
We have upgraded es 5.5 to 6.4 according to https://www.elastic.co/guide/en/elasticsearch/reference/current/restart-upgrade.html
But after upgrade below error is there :
[2018-08-29T14:42:44,446][ERROR][o.e.b.Bootstrap ] [es-master] node validation exception
[1] bootstrap checks failed
[1]: system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk

[2018-08-29T14:42:44,670][INFO ][o.e.x.m.j.p.NativeController] Native controller process has stopped - no new native processes can be started
If we set bootstrap.memory_lock: true and bootstrap.seccomp: false in elasticsearch.yml file then below error is present which was not present in 5.5 version
