It is 6.0.35 and it still produces this error, even after increasing the Xmx to 4g, we have installed tomcat 6.0.33 and each time we install the cloudstack it does not sense the installed 6.0.33 and attempts to install 6.0.35 as it is dependent on it. Silly solution is that we scheduled a daily restart @ 2PM through a cron job!!!! But first you have to "killall jvsc" then restart the management server.
What we are considering is to migrate the management server to CentOS 6.5 it comes with tomcat 6.0.24 and mysql 5.1, we attempted to restore the dump on a pilot environment and it worked. If someone else has a better solution than this would you please share it?

Issue... So I just checked my tomcat version and we are running 6.0.35 which must be the default that comes with Ubuntu 12.04 out of the box. Our memory settings are as follows: 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 -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/var/log/cloudstack/management/ -XX:PermSize=512M -XX:MaxPermSize=800m" So what version of tomcat are you running 6.0.35 or 6.0.33? > Subject: RE: Interesting 4.2.1.
