Hi, With logstash 5.0.0 on centos 7.2 using the elastic rpm, our logstash runs like this: usr/bin/java -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -XX:+DisableExplicitGC -Djava.awt.headless=true -Dfile.encoding=UTF-8 -XX:+HeapDumpOnOutOfMemoryError -Djava.io.tmpdir=$HOME -XX:HeapDumpPath=/dev/null -Xmx1g -Xms256m -Xss2048k -Djffi.boot.library.path=/usr/share/logstash/vendor/jruby/lib/jni -Xbootclasspath/a:/usr/share/logstash/vendor/jruby/lib/jruby.jar -classpath : -Djruby.home=/usr/share/logstash/vendor/jruby -Djruby.lib=/usr/share/logstash/vendor/jruby/lib -Djruby.script=jruby -Djruby.shell=/bin/sh org.jruby.Main --1.9 /usr/share/logstash/lib/bootstrap/environment.rb logstash/runner.rb --path.settings /etc/logstash [root@zd020 logstash]# I want to increase the heapsize to 4g, so I set LS\_HEAP\_SIZE=4g in /etc/sysconfig/logstash then ran $LS\_HOME/bin/system-install followed by a restart of logstash. But -Xmx stayed at 1g, in other words the setting was not applied. I tried the same thing by adding LS\_HEAP\_SIZE to /etc/logstash/startup.options but the result was the same. I verified using visualVM that indeed the heapsize is still limited to 1g. I did a grep for LS\_HEAP\_SIZE IN $LS\_HOME/bin but the only script that seems to use that setting is a dos/windows batch script. Perhaps the documentation is not correct in this area? How should I increase the heap that logstash 5 is allowed to use ? ---

Logstash 5.0 does not use `/etc/sysconfig/logsgtash`. It uses [`/etc/logstash/jvm.options`](https://www.elastic.co/guide/en/logstash/5.0/config-setting-files.html), mirroring how Elasticsearch 5.0 handles jvm settings. This change is especially important as it allows the JVM locale to be set easily. Try putting your heap settings in there. ---

indeed that does work (although not with ls\_heap\_size). It seems the documentation for logstash 5 is not correct since it still refers to ls\_heap\_size in many places. thanks for the pointer. ---

Please share any links that point to `/etc/sysconfig/logstash` and/or `LS_HEAP_SIZE` (which is still usable, if launching exclusively from the command-line. ---

I think this is all of them: [https://www.elastic.co/search?q="ls\_heap\_size"§ion=Docs%2FLogstash%2FReference%2F5.0](https://www.elastic.co/search?q=%22ls_heap_size%22§ion=Docs%2FLogstash%2FReference%2F5.0) ---
