Zimbra 4.5.5 Multi-server installation on CentOS5

[bejelith]

i have a problem with a multiserver installation...

that's my environment...
(i have a zone datanet.it in my LAN with MX, every server have 2GB of ram (hp proliant))

Server A:
zimbra_ldap (ldap master)

Server B:
zimbra_ldap (ldap slave)
zimbra_core
zimbra_store
zimbra_logger
zimbra_mta
zimbra_apache
zimbra_spell

the install process end well,
i start the master LDAP on server A, and it's ok

then i go to start zimbra services on server B:

zmcontrol start
Host zimbramta.datanet.it
        Starting ldap...Done.
        Starting logger...Done.
        Starting mailbox...Done.
        Starting imapproxy...Done.
        Starting antispam...Done.
        Starting antivirus...Done.
        Starting spell...Done.
        Starting mta...Done.
[zimbra@ZimbraMTA opt]$

All seems good... but:

http://IP:80 -> unable to connect!!

looking at netstat...

netstat -l -p -n

Take a look at /opt/zimbra/log/mailbox.log and /opt/zimbra/tomcat/logs/catalina.out to find out why tomcat exited so quickly.
