I would recommend: 1) drop tomcat3 script from the system 1.1) remove it from autostart 2) run `sudo killall java` 3) use this script https://github.com/apache/openmeetings/blob/master/openmeetings-server/src/main/assembly/scripts/openmeetings.service (bundled with OM) as described here https://github.com/apache/openmeetings/blob/master/openmeetings-server/src/main/assembly/scripts/openmeetings.service#L15 correct paths lines 28-30, 34, 35 modify line 31 set `-Xmx=8G` (this should be enough)
