Hi Keerthiraja, We are on 4.3.0.2 - So I am not sure it the tomcat6-nonssl.conf differs. I looked at your JAVA_OPTS line and mine,
Your Line: JAVA_OPTS="-Djava.awt.headless=true -Dcom.sun.management.jmxremote=false -Xmx2g -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/var/log/cloudstack/management/ -XX:PermSize=512M -XX:MaxPermSize=800m -Djava.security.properties=/etc/cloudstack/management/java.security.ciphers" Mine: JAVA_OPTS="-Djava.awt.headless=true -Dcom.sun.management.jmxremote.port=45219 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Xmx4g -Xms2g -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/var/log/cloudstack/management/ -XX:PermSize=512M -XX:MaxPermSize=800m" There are some options missing, but I also do not see a "-Xms" line in yours. I will put 4.5.1 in Lab and see what happens. My ACS MS has 8GB RAM, that is why I have -Xmx4g Regards, Timothy Lothering Solutions Architect Managed Services T: +27877415535 F: +27877415100 C: +27824904099 E: tlother...@datacentrix.co.za DISCLAIMER NOTICE: Everything in this e-mail and any attachments relating to the official business of Datacentrix Holdings Ltd. and its subsidiaries ('Datacentrix') is proprietary to Datacentrix.

After I install the CS with 4GB base memory I could not able to start the server. I scale the memory upto 12GB still I could not able to start the ACS. In /var/log/cloudstack/management/catalina.out I could see error as Can't start up: not enough memory Can't start up: not enough memory Can't start up: not enough memory Can't start up: not enough memory Can't start up: not enough memory Can't start up: not enough memory Can't start up: not enough memory Can't start up: not enough memory Can't start up: not enough memory Can't start up: not enough memory Is I missing anything. In the default file of below I could see the java value as default. tomcat6.conf -> /etc/cloudstack/management/tomcat6-nonssl.conf JAVA_OPTS="-Djava.awt.headless=true -Dcom.sun.management.jmxremote=false -Xmx2g -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/var/log/cloudstack/management/ -XX:PermSize=512M -XX:MaxPermSize=800m -Djava.security.properties=/etc/cloudstack/management/java.security.ciphers" Kindly let me know if any one found this issue. I even tried by increasing the -Xmx2g into 4g still I don't see any improvement. Thanks, Keerthi
