    Default Zimbra - excessive memory requirements for java/mysql

    Hi guys,

    Need your help here, please.

    I have attached screenshot about what is going on on my system.

    I currently run:

    Release 7.0.0_BETA2_2897.UBUNTU10_64 UBUNTU10_64 FOSS edition.

    The system has got 80GB fast HDD and 4GB RAM. Zimbra uses pretty much all the memory and I struggle to tweak it. On a different system I was able to take it down to about 1.3GB memory usage.

    I have tried the following:

    # zmlocalconfig -e mailboxd_java_options=”-server -Djava.awt.headless=true -XX:+UseConcMarkSweepGC -XX:NewRatio=2 -XX:PermSize=128m \
    -XX:MaxPermSize=128m -XX:SoftRefLRUPolicyMSPerMB=1 -Xms128m -Xmx128m”
    # zmlocalconfig -e tomcat_java_heap_memory_percent=5
    # zmlocalconfig -e zmmtaconfig_interval=3600
    # zmlocalconfig -e zmstat_interval=300
    # zmlocalconfig -e mailboxd_java_heap_memory_percent=5
    # zmlocalconfig -e mailboxd_java_heap_new_size_percent=5
    # zmlocalconfig -e ldap_common_threads=16
    # zmlocalconfig -e ldap_common_toolthreads=8
    # zmlocalconfig -e ldap_db_cachesize=50000
    # zmlocalconfig -e ldap_db_idlcachesize=50000
    # zmlocalconfig -e ldap_db_dncachesize=0
    # zmlocalconfig -e zimbra_zmjava_options=”-Xms128m -Xmx128m”
    # zmprov mcf zimbraMessageCacheSize 5000

    but nothing is helping.

    Any ideas guys?

    Many thanks.
