This looks like a JDK bug, which java version and OS are you running on? For reference, this is likely to be the reported JDK bug: [https://bugs.java.com/bugdatabase/view\_bug.do?bug\_id=JDK-8239559](https://bugs.java.com/bugdatabase/view_bug.do?bug_id=JDK-8239559) ---

i had a similar problem. it was something to do with the jvm.options file. i pulled a clean jvm.options file from the git repository and replaced the one in the /etc/elasticsearch folder. i adjusted the settings in the new clean one. and everything came right back up. ---
