Hi all, New to Logstash and Elasticsearch so pardon any silliness on my end with this configuration issue I'm currently having. I'm receiving the following error when I try to startup the elasticsearch as suggested via the guide linked below the following error code: [root@server01 ~]# service elasticsearch start Starting elasticsearch: [OK] [root@server01 ~]# Exception in thread "main" java.lang.ExceptionInInitializerError at java.lang.Class.initializeClass(libgcj.so.10) at org.elasticsearch.bootstrap.Bootstrap.main(Bootstrap.java:155) at org.elasticsearch.bootstrap.ElasticSearch.main(ElasticSearch.java:32) Caused by: java.lang.UnsupportedOperationException: gnu::java::lang:: management::VMMemoryMXBeanImpl::getNonHeapMemoryUsage () not implemented at gnu.java.lang.management.VMMemoryMXBeanImpl.getNonHeapMemoryUsage( libgcj.so.10) at gnu.java.lang.management.MemoryMXBeanImpl.getNonHeapMemoryUsage(libgcj .so.10) at org.elasticsearch.monitor.jvm.JvmInfo.(JvmInfo.java:69) at java.lang.Class.initializeClass(libgcj.so.10) ...2 more The Guide: [http://blog.basefarm.com/blog/how-to-install-logstash-with-kibana-interface-on-rhel/](http://blog.basefarm.com/blog/how-to-install-logstash-with-kibana-interface-on-rhel/) I stepped through the instructions exactly and installed ElasticSearch via the sites RPM on CentOS 6.0 I have added the following to: /usr/lib/sysctl.d/elasticsearch.conf ES\_MIN\_MEM=512m ES\_MAX\_MEM=1024m As well modified the elasticsearch.in.sh file which got it a bit further in the startup though I'm not certain it's actually made a true difference as I'm still receiving the above error: source /usr/lib/sysctl.d/elasticsearch.conf if ["x$ES\_MIN\_MEM" = "x"]; then ES\_MIN\_MEM=512m fi if ["x$ES\_MAX\_MEM" = "x"]; then ES\_MAX\_MEM=1024m fi I'd be happy to provide any additional information if anyone has a thought as to where I might have gone wrong. Currently installed is Nginx, Logstash, and ElasticSearch. Per the guide once complete it should be a working instance.... 🙂 Very much appreciate any help I can get and for you all taking any time what-so-ever to help me in getting this online. If I do end up identifying my problem which I have thus far looked over, I will be sure to update this post as well. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

What java version are you using? Also it's better to set min and max memory to be the same for ES.
