Without knowing the application I would strongly estimate that it is an application bug if it requests a block of 2 GB memory. It might be a good idea to monitor the JVM and its memory management with JMX-tools like jconsole (X11) or LambdaProbe (Tomcat). > CATALINA_OPTS="-server -XX:+UseParallelGC -Xms2048m -Xmx2048m > -XX:MaxPermSize=1024m -XX:+CMSClassUnloadingEnabled > -XX:+CMSPermGenSweepingEnabled -Djava.awt.headless=true" We are using in our standard setups some more parameters although I'm not sure if they are necessary always or just still valid, e.g.: # Maximum Size of new generation; default: function of NewRatio JAVA_OPTS="$JAVA_OPTS "-XX:MaxNewSize=400m # Default size of new generation; default: 30% larger JAVA_OPTS="$JAVA_OPTS "-XX:NewSize=400m # Ratio of new/old generation sizes; default: 8 JAVA_OPTS="$JAVA_OPTS "-XX:NewRatio=3 JAVA_OPTS="$JAVA_OPTS "-XX:+UseParNewGC Here you find some parameter docs: http://java.sun.com/javase/6/docs/technotes/tools/solaris/java.html http://java.sun.com/javase/technologies/hotspot/vmoptions.jsp Generally I would ask the application vendor for suggested parameters.
