I'm running 3 mgmt servers on 4.2.1, haven't seen any issues like that. You can send along your memory settings... here's what I'm running:
JAVA_OPTS="-Djava.awt.headless=true -Dcom.sun.management.jmxremote.port=45219 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Xmx2g -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/var/log/cloudstack/management/ -XX:PermSize=512M -XX:MaxPermSize=800m On Mon, Mar 31, 2014 at 9:33 AM, Michael Phillips <mphilli7...@hotmail.com> wrote: > So I have a redundant pair of management servers running on 4.2.1.
