I am installing ES on a hardened system and I am having issues with running my ES. When I try to run ES i get this error: unable to load JNA native support library, native methods will be disabled. java.lang.UnsatisfiedLinkError: /tmp/jna--1985354563/jna2511322471324368372.tmp: /tmp/jna--1985354563/jna2511322471324368372.tmp: failed to map segment from shared object: Operation not permitted at java.lang.ClassLoader$NativeLibrary.load(Native Method) ~[?:1.8.0\_211] at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1941) ~[?:1.8.0\_211] at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1824) ~[?:1.8.0\_211] at java.lang.Runtime.load0(Runtime.java:809) ~[?:1.8.0\_211] at java.lang.System.load(System.java:1086) ~[?:1.8.0\_211] at com.sun.jna.Native.loadNativeDispatchLibraryFromClasspath(Native.java:947) ~[jna-4.5.1.jar:4.5.1 (b0)] at com.sun.jna.Native.loadNativeDispatchLibrary(Native.java:922) ~[jna-4.5.1.jar:4.5.1 (b0)] at com.sun.jna.Native.(Native.java:190) ~[jna-4.5.1.jar:4.5.1 (b0)] at java.lang.Class.forName0(Native Method) ~[?:1.8.0\_211] at java.lang.Class.forName(Class.java:264) ~[?:1.8.0\_211] at org.elasticsearch.bootstrap.Natives.(Natives.java:45) [elasticsearch-6.4.3.jar:6.4.3] at org.elasticsearch.bootstrap.Bootstrap.initializeNatives(Bootstrap.java:103) [elasticsearch-6.4.3.jar:6.4.3] at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:171) [elasticsearch-6.4.3.jar:6.4.3] at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:326) [elasticsearch-6.4.3.jar:6.4.3] at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:136) [elasticsearch-6.4.3.jar:6.4.3] at org.elasticsearch.bootstrap.Elasticsearch.execute(Elasticsearch.java:127) [elasticsearch-6.4.3.jar:6.4.3] at org.elasticsearch.cli.EnvironmentAwareCommand.execute(EnvironmentAwareCommand.java:86) [elasticsearch-6.4.3.jar:6.4.3] at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:124) [elasticsearch-cli-6.4.3.jar:6.4.3] at org.elasticsearch.cli.Command.main(Command.java:90) [elasticsearch-cli-6.4.3.jar:6.4.3] at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:93) [elasticsearch-6.4.3.jar:6.4.3] at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:86) [elasticsearch-6.4.3.jar:6.4.3] I have created my environment variable: export ES\_JAVA\_OPTS=-Djna.tmpdir=/data/elasticsearch/tmp I remounted my data directory to exec I am not allowed to remount my /tmp folder to exec (security reasons) as this does work for me.. I've updated my /etc/sysconfig/elasticsearch and inputted ES\_JAVA\_OPTS=-Djna.tmpdir=/data/elasticsearch/tmp I have also updated my jvm.options and set -Djna.tmpdir=/data/elasticsearch/tmp but it seems whenever i try to start elasticsearch it keeps on looking at the /tmp folder any help would be great ---

Can you share the log line that shows the JVM arguments at startup? It's one of the first log lines, but it would be after the exception message that you show. ---
