Hi guys.

I setup a multiserver installation of Zimbra in 3 hosts this way:

1. ZLDAP: ldap, zmconfigd, stats and snmp
2. ZMTA: mta, antivirus, antispam, zmconfigd, stats and snmp
3. ZMAILSTORE: mailbox, spell, logger, zmconfigd, stats and snmp

On the administration GUI all those services are running except by mailbox service on ZMAILSTORE host. But in the console the service appears to be running too.
[zimbra@zmailstore ~]$ zmcontrol status
Host zmailstore.***.***
	mailbox                 Running

[zimbra@zmailstore ~]$ zmmailboxdctl status
mailboxd is running.

[zimbra@zmailstore ~]$ ps aux | grep $(cat log/zmmailboxd_java.pid) | grep -v grep

The only "error" log I got was a sequence of these lines in /var/log/messages (I didn't get any erros in mailbox.log):
zmconfigd CRITICAL [1516-MainThread-3] mailbox start initiated from zmconfigd
zmconfigd CRITICAL [1516-MainThread-3] mailbox restart initiated from zmconfigd
I'm running this release of Zimbra in servers: 7.2.0_GA_2669.RHEL6_64_20120410002025 UNKNOWN_64 FOSS edition.

My OS and kernel are:
CentOS Linux release 6.0 (Final)
Obs: the rsyslog and ssh keys are working fine.
