    Default Upgrade to 4.0.3 and mail delivery slows to a crawl

    We finally upgraded to the latest version over the course of this weekend. I received a report of slow mail delivery, and when I logged in to take a look I found that the mail delivery has all but come to a standstill. Have a look:

    Code:
    [zimbra@hostname bin]$ ./qshape | head

    I've tried turning off antispam/antivirus thinking the scanning was causing the problem, but that doesn't seem to speed things up at all. My queues are continuing to grow at a very rapid rate. We're running ZCS Open Source 4.0.3 on CentOS 4.3. Anyone seen similar problems?

    Default

    You don't say what else is running on that server but could this be the problem? If that's not it see what's consuming your cpu cycles.

    Default Not much else

    Other than Zimbra, I'm only running a local caching nameserver (solely for Zimbra's use) and an unused VMware server. According to `top`, the server's procs (dual P4) are approximately 50% idle with load averages around 5.

    Default unicode_start

    Just to make sure, I checked for any unicode related processes:

    Code:
    [root@hostname log]# ps ax | grep unicode
    10309 pts/0    S+     0:00 grep unicode
    [root@hostname log]#
    also... here is my /etc/sysconfig/i18n file:

    Code:
    [root@hostname log]# cat /etc/sysconfig/i18n
    LANG="en_US.UTF-8"
    SUPPORTED="en_US.UTF-8:en_US:en"
    SYSFONT="latarcyrheb-sun16"
    [root@hostname log]#
    Should I remove the UTF-8 and just stick with en_US? Reboot afterwards?

    Question Upgraded OS

    Followup:

    I upgraded CentOS to latest and greatest including the newest kernel update. Deliveries were delayed by over 20 hours, but they're slowly dwindling down. Most of the 4000 remaining messages are in the active queue. At the current rate, it looks like queue will be back to normal sometime this afternoon.

    Any advice on how to speed up delivery for messages waiting in the active queue? I tried flushing, but that doesn't seem to help at all.
