Simply posting a log with no further information does not help. Unless you add more information on what the problem you are trying to solve it, you won't get much assistance.

Looks like something has shut the service down, as you mention. We can't say what, you'd need to consult your OS logs.

elasticsearch[16692]: /usr/share/elasticsearch/bin/elasticsearch-env: line 70: /etc/sysconfig/elasticsearch: Permission denied
