    This isn't a problem. The minimum recommended resources for a ZCS 8.x install are at least 4GB or RAM and (about) 110GB of HD space - that's irrespective any how many users you currently have on the server. Did you read the System Requirements before installing Zimbra?

    You need to add more resources to this server.

    Hi Handaka,

    For installing Zimbra mail sever the VMWare recommending minimum 4 GB RAM for a normal speed. Once you increase the size of RAm and check the speed again.

    With Regards
    Anish ... :-)

    Thanks for your reply. i have read the article, but I just install zimbra server for serve 25 access simultan via web interface. is it possible for me to install zcs 8.x.x with hardware specification likes above? and about the hdd capacity? I have allocated 150 GB from 110 GB minimum hdd recomended, but it still been full in less than 1 hour without any mail transaction. thanks.

    No, it won't run very well with that configuration and certainly not with twenty-five users. You need the recommended minimum 4GB of real RAM not on-demand.

    That isn't normal, ZCS will only use disk space when nail is coming into the system. I'd suggest you investigate what is consuming that disk space.

    Hi there,

    I spent several weeks getting Zimbra to work in OpenVZ on Ubuntu 12.04 on a sever with 3GB of ram. I've been able to get it working and stable!
    The disk space is filling up because of errors that are being recorded in /opt/zimbra/zmstat/zmstat.out
    The errors are being caused by a bug in the current version of sysstats for Ubuntu 12.04. From what I understand, anyone using Ubuntu 12.04 should be having this problem.

    Here is the fix:
    #Use an older version of sysstats.
    #Download LUCID version here with wget:
    wget https://launchpad.net/ubuntu/+source....6-2_amd64.deb
    #Remove the older version:
    sudo apt-get remove --purge sysstats
    #Install newer version:
    sudo dpkg -i sysstat_9.0.6-2_amd64.deb

    #After installed Lock package from upgrades:
    sudo apt-mark hold sysstas

    #In the future, once the bug has been fixed with the standard version of sysstats for 12.04, you can remove the hold on upgrading it with:
    sudo apt-mark unhold sysstats

    I found the answer here:
    Use of uninitialized value $line in pattern match (m//) at /opt/zimbra/libexec/zmstat

    I had to also make several tweaks in order for it to run in 3GB of memory. They should also work for 2GB.
    Here are the Tweaks I had to do to get it to run in OpenVZ:

    #You need to remove anything that has to do with sendmail and apache before installing, as I had several problems with apache conflicts:
    sudo apt-get remove --purge apache2 apache2-doc apache2-mpm-prefork apache2-utils apache2.2-bin apache2.2-common bind9 bind9-host bind9utils sendmail sendmail-base sendmail-bin sendmail-cf sendmail-doc-sensitive mda rmail samba bsd-mailx

    #Install Dependancies:
    sudo apt-get install netcat-openbsd libgmp3c2 sysstat sqlite3 pax

    #Install Zimbra

    #Once installed, shutdown all services:
    sudo su zimbra
    zmcontrol stop

    #As Root:
    su root

    #In /opt/zimbra/conf/amavisd.conf.in (and amavisd.conf) edit and change $max_servers = 2 from the default of 10.
    $max_servers = 2; # number of pre-forked children (2..15 is common)

    #Also reduce the number of connections in /opt/zimbra/conf/my.cnf
    thread_cache_size = 30
    max_connections = 30

    #As zimbra:
    su zimbra
    #If there are only a couple of active mailboxes reduce the ram footprint for mailboxd.
    zmlocalconfig -e mailboxd_java_heap_size=768
    #and fix SQL:
    zmlocalconfig -e mysql_memory_percent=15

    #When done:
    zmcontrol restart

    I found this info here:
    Zimbra in a small box - atp

    Hope thats of some help! The only problem I'm having now is "localhost" and "127.0.0.1" is injected into the headers of my emails. This is causing them to be marked spam by a lot of services. From what I understand, most Zimbra installs do this...
