CS agent consumes a lot of RAM
Hi all,
on CS 4.2 we have the problem that the agent on the hypervisors consumes a lot of memory sometimes.
If that happens the OS starts to kill the virtual machines.
Are there any solutions out there or some java configurations for the agent?
Thanks and regards,
Ingo

That’s right you can pass in -Xmx to restrict maximum JVM heap size. An issue related to cloudstack agent was recently fixed on 4.3/4.4/4.5/master;

This is what I see on ACS 4.4.2, so perhaps you make same/similar changes,
with limiting java RAM usage etc:
[root@compute1 ~]# grep -ir Xmx /etc/
/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"
/etc/cloudstack/management/tomcat6.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"
/etc/cloudstack/management/tomcat6-ssl.conf:JAVA_OPTS="-Djava.awt.headless=true
-Dcom.sun.management.jmxremote=false
-Djavax.net.ssl.trustStore=/etc/cloudstack/management/cloudmanagementserver.keystore
-Djavax.net.ssl.trustStorePassword=vmops.com -Xmx2g
-XX:+HeapDumpOnOutOfMemoryError
-XX:HeapDumpPath=/var/log/cloudstack/management/ -XX:MaxPermSize=800m

The upgrade to 4.4 is planned but we are looking for a short term solution.
