    Default Network M2 slow/"slow to respond" issues

    I have Zimbra M2 Network version installed on a dual p4 system with 1 gig of ram & FC4. "top" usually reports cpu usage of 1% or less, with occasional spikes to 80-90%. Despite this, I see massive slowdowns in performance from time to time as well as these issues:
    -attachments don't send in FF1.5
    -right click menus don't work sometimes
    -user login fails to finish sometimes (welcome screen just sits
    with the animation going...................)
    -can't delete messages from inbox somtimes or takes 1+ minute
    -frequently get the error message "The server appears to be slow to
    respond, and may be unavailable. Press the button to cancel your
    request.").
    -also "Could not complete operation." errors
    name - TypeError
    message - 'undefined' is null or not an object
    number - -2146823281
    description - 'undefined' is null or not an object

    Strangly enough, if I "zmcontrol stop" then "zmcontrol start" the server, most of these problems seem to dissapear for a while (large copies/deletes still cause problems for FireFox). For instance, I couldn't delete messages from my folder until I bounced the server, then it functioned quickly until I let it run for 30ish minutes. After that time it was back to being slow. My imap connection with Thunderbird also seemed to work a lot better after the restart, but sometimes it also seems to have a lot of trouble dealing with Zimbra.

    From what I've read in other threads, many of these problems have been fixed in the recent developer builds which have been posted for testing, but apparently these are not compatible with the Network-M2 release. Is there any way to get an update for the Network version as well?
    If not, can I remove the Network version and install the normal version without losing all of the accounts I've imported?
    For those of us trying to use the Network version in a *real* environment, it is a bit frustrating to run into all of these bugs yet have no recourse.

    thanks

    Sam, Your right that the current dev build fixes most of these issues. To be fair FF 1.5 was not released when we pushed M2. Internally we are working on plans to release Network testing builds etc. I'll PM you with some more details to help you solve your immediate needs.

    I'd like to note that M3 seems to be a LOT smoother than M2. After testing with large message deletions and various other things that caused problems in M2, I've yet to see anything unexpected from M3. Performance also seems to be better and consistent.

    thanks Zimbra team!

    Okay, okay, where is this "M3" so that I too, may have a modern working system?

    Finally actually bothered trying this out, and the performance is abysmal, and the lack
    of client-feedback is scary. Hung send window/with attachment coupled with
    "done" status is giving contrary info, it's confusing.

    But, this software is really really so very promising, i'm quite excited by it.

    Considering what it does, I'm not upset or anything. But I should very much like to see it work.


    PS,
    Server (dedicated, nothing else running)
    dual 700mhz xeon, 1 gig registered, small scsi raid-0 array. centos 4.2 fully
    patched. Just to try it out.

    Clients,
    Mozilla 1.7.12- Apple Powerbook G4 (second gen),
    Firefox 1.5, Linux x86, moble athlonxp 2600,

    I think the link Kevin posted above will get you to something similar to what I am using. And yeah, all of those problems you mentioned have gone away. (SWEET!)

    Bummer

    Installed M3,

    Much faster, but sending email formatted html, with attachment, ff 1.5 on linux
    still hangs.

    I'll rebuild the machine a more closely supported build tomorrow. It's a CentOS
    4.2 machine now. I'll put FC4 on there.

    G'night!
    and keep up the good work!

    PS,. it still says "done" in the status area, while hung. not very truthful

    I just tested the html formatting + attachments, and got the same problem Cpm mentioned above. Firefox 1.5 reports "Sending request to......"
    While it is "sending" this request, all of firefox seems to sort of freeze.

    Eventually a window pops up saying:
    "A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete."

    If I click continue right away, firefox goes back into a super busy/frozen state. If I wait a long time, then click continue, it goes back to acting like normal. Interestingly, the email sends properly!
