I experience the same issue. Sometimes elasticsearch just stopps, but sadly the daemon does not - so it does not automatically restart.
System:
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.04.2 LTS
Release: 16.04
Codename: xenial
Elasticsearch:
$ curl localhost:9200
{
"name" : "xcRongv",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "_vh8wSYVQt2tNPlzQJYjVA",
"version" : {
"number" : "5.3.2",
"build_hash" : "3068195",
"build_date" : "2017-04-24T16:15:59.481Z",
"build_snapshot" : false,
"lucene_version" : "6.4.2"
},
"tagline" : "You Know, for Search"
}
Java:
$ java -version
openjdk version "1.8.0_121"
OpenJDK Runtime Environment (build 1.8.0_121-8u121-b13-0ubuntu1.16.04.2-b13)
OpenJDK 64-Bit Server VM (build 25.121-b13, mixed mode)
The error is similiar to the other errors mentioned here. Syslog only mentions:
systemd[1]: elasticsearch.service: Main process exited, code=killed, status=6/ABRT
And in /tmp/hs_err_pid1110.log
