    Default Big problems using 6.04

    Hello all,
    We migrated to 6.04 and of december. We were running 5.14 without any problem. Now, from the beginning of the year, we've many problems :

    After a few days, impossible to connect to admin console. The login page is coming but after having entered the admin login and password, the page is loading without interruption...

    then, many users came to me because they could not connect anymore using imap or webmail ...

    I checked my logs and here's what I found :

    2010-01-19 08:33:53,470 INFO [ImapServer-1567] [ip=192.168.100.101;] ProtocolHandler - Exception occurred while handling connection

    Now, I stopped and I'm restarting the zmcontrols . I will then check the logs again ...

    Hello,
    Thanks for the enquiry. My email server is running in a wmare virtual machine. The virtual machine has 1.87 GB Ram for my email server and it says that 356 MB is actually used.

    For the load, where can I verify ? In my VM Admin console, my server seems to be very quiet : only 0.0029 GhZ of my processor is used for the while. Or is there anoter way to verify ? only have 15 guys using the email server.

    What is the underlying storage ? How many other VMs are running on the server ? How busy is the VM host ?

    /dev/mapper/Ubuntu-root
    49242944 12961120 33780400 28% /
    varrun 950644 56 950588 1% /var/run
    varlock 950644 4 950640 1% /var/lock
    udev 950644 52 950592 1% /dev
    devshm 950644 0 950644 0% /dev/shm
    /dev/sda5 233303 13792 207064 7% /boot

    VMware what? VMware Server, if so, what host OS and hard drive setup?

    Zimbra needs a good amount of disk IO between the logger and email activity. You can try disabling the logger and see if that improves your performance.

    Hello,
    Thanks for the help. I'm ready to make all the tests I can, but keep in mind that before migrating, I had really no problem. So, I don't know if version 6.04 need so much processor time, disk IO and RAM that know I've so many problems ?

    Whats your load average?
    Have you restarted the Zimbra services since you disabled the logger (which is required to stop the logger)?
    How much RAM do you have?
    How many active mailboxes?
