    Default Zimbra on 32-bit vs 64-bit Server

    Hello,

    is there any advantage of installing Zimbra on a 64bit host/os
    (except that probably a 64bit OS does support more RAM)?


    Thank's a lot!

    John

    That would depend on your configuration and you haven't really given much detail, have you?

    The main reason would be that Zimbra will eventually be shipped only in 64bit versions (don't ask when) so you might as well do it now.

    I guess so, but if you don't tell when, it doesn't help much=). I going to install Zimbra into virtual machine, Proxmox VE. Currently I have 70 users with up to 100-150 eventually. And I'm short on resourses (who isn't?).
    I tried to install 64 bit version first, and although documentation says minimum memory requirement is 2GB (I allocated just as much for ths vm), it actually failed to install with errors like "Couldn't create Java virtual machine". 32 bit applications eat less memory in general, so now I'm considering if it worth the try.

    edit: I allocated 3Gb memory to 32 bit version and it still gives errors during installation:
    Code:
    Notify Zimbra of your installation? [Yes] no
    Notification skipped
    Starting servers...Could not create the Java virtual machine.
    mkdir : No such file or directory at /opt/zimbra/bin/zmcontrol line 35

    ok, that's frustrating. I allocated 4GB and still can't get Zimbra to install correctly. Has anyone actually managed to install Zimbra 6.0.3 into Proxmox/Openvz container?

    64bits, is just the future standart, but sincerly it doesn't improve performances 'yet'.
    I only use 64bits OS for memory limitations at the moment.

    Yeah we use OpenVZ. You need to check /proc/user_beancounters in the container and see what memory option is reaching its limit - the ones with fail count greater than zero need adjusting. You can adjust them in the host with vzctl set VEID --option NEWSOFT:NEWHARDLIMIT --save
    Also, I would suggest you be careful with the meminfo command, and the JVM will automatically consume a certain percentage of available memory, and it believes that meminfo is the file to ask how much memory you have (OpenVZ makes this file meaningless). So use the meminfo parameter to adjust how much memory the JVM will believe it can consume. If you tweak that right, then the JVM will start, even with a small amount of actual memory. Odds on you are running out of privvmpages as well.
