I'm running elastic search with the elasticsearch service wrapper. It is running with the following commandline: Service: /usr/local/elasticsearch/bin/service/exec/elasticsearch-linux-x86-64 / usr/local/elasticsearch/bin/service/elasticsearch.conf wrapper.syslog.ident=elasticsearch wrapper.pidfile=/usr/local/ elasticsearch/bin/service/./elasticsearch.pid wrapper.name=elasticsearch wrapper.displayname=ElasticSearch wrapper.daemonize=TRUE wrapper.statusfile=/usr/local/elasticsearch/bin/ service/./elasticsearch.status wrapper.java.statusfile=/usr/local/ elasticsearch/bin/service/./elasticsearch.java.status Java app: java -Delasticsearch-service -Des-foreground=yes -Des.path.home=/usr/ local/elastisearch -Djline.enabled=true -XX:+UseParNewGC -XX: +UseConcMarkSweepGC -XX:+CMSParallelRemarkEnabled -XX:SurvivorRatio=8 - XX:MaxTenuringThreshold=1 -XX:CMSInitiatingOccupancyFraction=75 -XX: +UseCMSInitiatingOccupancyOnly -XX:+HeapDumpOnOutOfMemoryError - Xms128m -Xmx128m -Djava.library.path=/usr/local/elasticsearch/bin/ service/lib -classpath /usr/local/elastisearch/bin/service/lib/ wrapper.jar:/usr/local/elasticsearch/lib/elasticsearch-0.16.2.jar:/usr/ local/elasticsearch/lib/jline-0.9.94.jar:/usr/local/elasticsearch/lib/ jna-3.2.7.jar:/usr/local/elasticsearch/lib/log4j-1.2.15.jar:/usr/local/ elasticsearch/lib/lucene-analyzers-3.1.0.jar:/usr/local/elasticsearch/ lib/lucene-core-3.1.0.jar:/usr/local/elasticsearch/lib/lucene- highlighter-3.1.0.jar:/usr/local/elasticsearch/lib/lucene- memory-3.1.0.jar:/usr/local/elasticsearch/lib/lucene- queries-3.1.0.jar:/usr/local/elasticsearch/lib/sigar/sigar-1.6.4.jar - Dwrapper.key=\_W0gBuF6pmW0y2lL -Dwrapper.port=32000 - Dwrapper.jvm.port.min=31000 -Dwrapper.jvm.port.max=31999 - Dwrapper.disable\_console\_input=TRUE -Dwrapper.pid=32072 - Dwrapper.version=3.5.6 -Dwrapper.native\_library=wrapper - Dwrapper.service=TRUE -Dwrapper.cpu.timeout=10 -Dwrapper.jvmid=1 org.tanukisoftware.wrapper.WrapperSimpleApp org.elasticsearch.bootstrap.Bootstrap However it is consuming 500 MB of reserved memory and 1GB of virtual memory. As you can see the heap sizes are set to 128m (min and max). I've tried to enable jconsole on the app by adding - Dcom.sun.management.jmxremote to the commandline and that has no effect either. Is the jvm somehow ignoring all these options? I'm very confused not just because it is not acting how I want it to but because my changes seem to have no effect on the app at all. If i raise the memory to 2GB the size doesn't change either. I really need help with this if anyone has any to offer. Thanks ---

When you set Xms and Xmx, it affects the _heap_ memory of the JVM, not all the memory used by the process. You can use the node info and stats API to see how its configured (info), and current values (stats).
