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?
