ENOMEM error on ES

Elastic Stack Elasticsearch
1

Hi all,

I just moved to start using elasticsearch as a non-root user. I am getting
this error at startup

[2014-08-08 22:38:17,768][WARN ][common.jna ] Unable to lock
JVM memory (ENOMEM). This can result in part of the JVM being swapped out.
Increase RLIMIT_MEMLOCK (limit).

Does anyone have experience with this error? I upped the file descriptor
limit and confirmed it through the ES API and OS level.

I am running ES 1.3.1

Thanks!

This is a warning, not an error.

As you can see, you allowed only 65536 bytes(!) for memory locking. You can
set this to unlimited if you are on Linux OS with memory overcommit.
