strange shared address book problem

[lk2oo3]

Hi all,
i've a strange problem with customer's shared address book.

Admin shares a address book with other users in the domain.
I'm shure that, if I reboot Ubuntu, before (sometimes next day) or later (last time near 2 weeks) there will be a moment in which users do not see the shared address book (customer calls me to solve..).
To solve the problem, it is sufficient that admin access the domain and click on shared address book, to let other users see again shared contacts.
The problem raises again next ubuntu reboot (before or later..).
Now it happens with Zimbra 6.04, but the same was also with Zimbra 6.03 and 6.02.

Any suggestion on howto resolve / what check?

this is the scenario:
zimbra 6.04 Open Source Ed
ubuntu 64 8.04lts on vmware server 2.


Thanks in advance,
bye Luca

Today they have same problem (users cannot see admin shared address book).
I'm sure i did not make any OS reboot!!
I checked admin email and.. users have again their address book.

They told me that it happenned days ago.

any idea?
what should I check?

tnx in advance, Luca.

in the meanwhile i'll upgrade zimbra to 6.05, hoping it could help

Hello, only to tell you that

yesterday, before upgrading to new release, i noticed ubuntu had a file system problem on OS disk
(not on zimbra disk that is mounted on /opt directory)

on reboot Ubuntu required a manual fsck on OS disk and, after correcting 4/5 problems on file system,
it was possible to upgrade zimbra to 6.05

Now Zimbra is working well.
All services are on, no problems mailed to admin.
Hope that my customer file system problem was the really "address book problem" source.

tnx again,
hope no, but in case, i'll post new problems.

bye luca.

Again same problem (users cannot see admin shared address book).
no server reboot!!
I checked admin email and.. users have again their address book.

They told me that it happenned days ago.

It is becoming frustating.

i'm checking zimbra and system logs, but cannot find anything useful to understand.

please give me any suggestion
tnx in advance, Luca.

Code:account.ACCOUNT_INACTIVE

and the obvious question is: why admin account is inactive???
maybe when i login as admin it changes state from inactive to active and it solves the problem? and from now on, admin shared contact turn again available for all... until next same condicion that puts inactive admin account..?

2.
in the logs i also found many pop3 access attempts, from various ip addresses, with random username: maybe someone is trying to generate an exploit that at the end puts admin account in inactive state?

hoping someone may help,
i'm trying to block pop traffic via firewall rule

tnx, bye, luca.
