    Default Update or patch the server or not?

    Hi,

    it's interesting that after running ZCS for almost 2 years, only now it crossed my mind, that it might not be bad beside ZCS update to also update server OS, too.
    What do you think?
    My OS is Ubuntu 8.04 64-bit - should patch it too, or not?

    And if YES, should I do it prior to ZCS upgrade, or after?

    thanx!

    Well, if its not broken, don't fix it

    But if you are so eager to do it:
    (1)Full backup the whole drive 1st if possible.
    (2)Upgrade OS
    (3)Upgrade Zimbra

    Well...
    I am not sure if everything is OK with my install. My ZCS is running on QuadCore XEON with 8 GB RAM and RAID 10 disk array, 1 GB direct attached to IP exchange in datacenter...processors are idling most of time (2-3% usage average), but most of clients with IMAP & Outlook 2007/2010 (or Thunderbird) experience infinite syncing, timeouts and switching to off-line from IMAP connection. Ok, all those have 3 GB+ mailbox size.

    So, if it's not hardware, nor networking issue...is it OS then?

    Othervise, it's working fine for all those years.

    3GB mailbox size you will have some kind of issue properly with any email client, especially if they have huge amount (1000+) of emails left in the inbox and not sort into sub folders. If they have huge sub folders, only do auto sync selectively.

    Windows indexing and email client indexing just make the problem worse if they are not sync frequent enough.

    One possible way to fix it, for imap user, is to actually delete the account within the email client, and recreate it. Then do a clean full sync with the server, that may improve the situation.
