I upgraded zimbra open from 6.0.6 to 6.0.7 and mailbox not hold started.
When services is started by zmcontrol start, mailbox is up but soon after is down.
The error in zimbra.log is:
Jun 19 12:03:11 netserver zmmailboxdmgr: manager woke up from wait on mailboxd/JVM with pid 20551
Jun 19 12:03:11 netserver zmmailboxdmgr: mailboxd/JVM exited twice in 33 seconds (tolerance=60)
