I stupidly tried to optimize my server using this how to:
Zimbra OCS on a OpenVZ VPS Server « Le Pig
Now my mailbox and my zmmailboxdctl are not running how can I fix it? I re-upgraded but the problem still exists and I don't quite know where to start.

antispam Running
ldap Running
logger Running
mailbox Stopped
zmmailboxdctl is not running.
mta Running
snmp Running
stats Running
zmconfigd Running
