mailbox stopped

[agd]

Hi, I'm having some trouble with mailbox services:

Jul 1 11:52:09 mail zimbramon[18083]: 18083:info: 2010-07-01 11:52:01, STATUS: mail.maildomain.com: mailbox: Stopped

Jul 1 11:51:56 mail zimbramon[15265]: 15265:err: Service status change: mail.maildomain.com mailbox changed from running to stopped
Jul 1 11:53:07 mail zimbramon[15265]: 15265:err: Service status change: mail.maildomain.com mailbox changed from stopped to running
Jul 1 13:06:10 mail zimbramon[15265]: 15265:err: Service status change: mail.maildomain.com mailbox changed from running to stopped
Jul 1 13:07:25 mail zimbramon[15265]: 15265:err: Service status change: mail.maildomain.com mailbox changed from stopped to running


any idea why this could be happening ?
The hardware is ok (memory, CPU and so on).

Regards,
AGD

Have you tried a zmcontrol stop and the zmcontrol start?

Yes, but the errors stills happens.

Anything of interest in /opt/zimbra/log/mailbox.log at the times when it stops?

Also, we'll need to know the version and OS at a minimum.

Hi, I upgraded from 5.0.11 to 5.0.23 then 6.0.7 and now seems to be everything ok.

Thanks !!
