Hi, I'm having trouble starting elastic on CentOS via the elasticsearch-service. I get the error "Could not reserve enough space for the object heap" I must say that I'm using a pretty low memory VPS, but I think that I should be able to run elastic anyway. for reference: the contents of my elasticsearch.conf: set.default.ES\_HOME=/opt/elasticsearch/elasticsearch-0.19.3 set.default.ES\_HEAP\_SIZE=256 set.default.ES\_MIN\_MEM=%ES\_HEAP\_SIZE% set.default.ES\_MAX\_MEM=%ES\_HEAP\_SIZE% #\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* # Wrapper Timeout Properties #\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* # How long to wait for the JVM to start (in seconds) wrapper.startup.timeout=300 # How long to wait for the JVM to stop (in seconds) wrapper.shutdown.timeout=300 # When a ping will timeout to consider the JVM hung (in seconds) wrapper.ping.timeout=300 #\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* # Wrapper Java Properties #\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* # Java Application wrapper.java.command=java # Tell the Wrapper to log the full generated Java command line. #wrapper.java.command.loglevel=INFO wrapper.java.mainclass=org.tanukisoftware.wrapper.WrapperSimpleApp wrapper.working.dir=%ES\_HOME% # Java Classpath (include wrapper.jar) Add class path elements as # needed starting from 1 wrapper.java.classpath.1=%ES\_HOME%/bin/service/lib/wrapper.jar wrapper.java.classpath.2=%ES\_HOME%/lib/elasticsearch\*.jar wrapper.java.classpath.3=%ES\_HOME%/lib/_.jar wrapper.java.classpath.4=%ES\_HOME%/lib/sigar/_.jar # Java Library Path (location of Wrapper.DLL or libwrapper.so) wrapper.java.library.path.1=%ES\_HOME%/bin/service/lib # Java Bits.
