Can you please check which process is eating memory?

Hey! Java is eating memory :) Output of "top" command, sorted by memory: ``` PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 3290 998 20 0 5276472 1.545g 21560 S 0.0 19.8 0:46.61 java 3559 998 20 0 4751644 1.216g 24380 S 0.3 15.6 1:05.52 java 3390 998 20 0 4240216 958184 21052 S 0.0 11.7 0:23.42 java 3221 998 20 0 3192664 772132 20736 S 0.0 9.4 0:23.18 java 3477 998 20 0 3654680 747276 21180 S 0.0 9.1 0:21.80 java ``` All memory used for Java: ``` $ ps aux | grep java | awk '{sum=sum+$6}; END {print sum/1024 " MB"}' 5248.3 MB ``` Java processes: ``` $ ps aux | grep java 998 3221 0.2 9.4 3192664 772268 ?

After 19 hours of running server, it has eaten more then 15% of RAM out of 6 Gb!

I think you don't need to worry about how much memory is 'consumed' until and unless your server starts crashing. With a perfectly optimal server, you will see 80~85% memory is being consumed all the time with resources. Anyways... you can specifically allocate JVM memory if you want for each component in Gluu Server. They are inside `/etc/default/` of Gluu-Server container. After adding these configuration, you need to restart your Gluu Server container. To give you a quick example... here is how it might looks like: ``` GLUU.[root@idp default]# pwd /etc/default GLUU.[root@idp default]# cat identity JAVA_HOME=/opt/jre JAVA=$JAVA_HOME/bin/java JAVA_OPTIONS="-server -Xms256m -XX:MaxMetaspaceSize=1000m -XX:+DisableExplicitGC -Dgluu.base=/etc/gluu -Dcatalina.base=/opt/gluu/jetty/identity -Dpython.home=/opt/jython -Dorg.eclipse.jetty.server.Request.maxFormContentSize=50000000" JETTY_HOME=/opt/jetty JETTY_BASE=/opt/gluu/jetty/identity JETTY_USER=jetty JETTY_ARGS="jetty.http.host=localhost jetty.http.port=8082" TMPDIR=/opt/jetty-9.3/temp export PYTHON_HOME=/opt/jython GLUU.[root@idp default]# ```
