Hi
with elasticsearch ver 2.20 and jdk 1.8.74 when elasticsearch start I see the followinf warning
[2016-02-22 12:16:00,140][WARN][bootstrap] unable to install
syscall filter: seccomp unavailable: requires kernel 3.5+ with CONFIG\_SECCOMP and CONFIG\_SECCOMP\_FILTER compiled in
I can find no help on the web for that message.
Has anyone find a similar message, do I have to worry about that?

You can safely ignore this message.
The meaning of the message is that Elasticsearch security module made an extra effort to revoke Linux process privileges to reduce so called "attack vector" for malevolent activities, but your Linux kernel is either too old or not able to offer that process privilege revoke API. That does not influence or harm the function of Elasticsearch.
You should only consider to run a more modern Linux.
