Big problems using 6.04

[forstera]

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 ...

How much memory does the server have ? What was the load on the server ?

[forstera]

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 ?

[forstera]

I've just anoter VM running. I'm not an ubuntu expert, so here's what I get about the storage in my mail server :

Filesystem 1K-blocks Used Available Use% Mounted on
/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

I dont know if it's what u need ?

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 ?

[forstera]

So, i stopped the logger service but no success in starting the web admin console.
MY HHD are in RAID 5. My Zimbra version is :
Release 6.0.4_GA_2038.UBUNTU6 UBUNTU6 FOSS edition.

For the os :
Description: Ubuntu 6.06.2 LTS
Release: 6.06
Codename: dapper

And for VmWare :
VMware Infrastructure Web AccessVersion 2.0.0
Build 128374V
Mware ServerVersion 2.0.1
Build 156745

My server
HP ProLiant DL360 G5
Processors Intel(R) Xeon(R) CPU 5130@2.00GHz1 x 2 Cores

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?
