Hello. Thank you all for your attention.

I am very new to this and although I managed to install Zimbra and run for a few months now I have this problem not solve.

The process "mailbox" stops after a few minutes, restarted proffers, but always stops again. With the command status zmcontrol this message: zmmailboxdctl is not running

I could check the logs file "Mailbox.log" has failed every time and this is what I found:
