I have a fresh install of 6.0.14_GA on a fresh install of Ubuntu 8.0.4 LTS and with zmcontrol start i get this:

Starting Zimbra...
Host mail.xxxxxx.com
Starting ldap...Done.
Starting zmconfigd...Done.
Starting logger...Done.
Starting mailbox...Done.
Starting antispam...Done.
Starting antivirus...Failed.
Starting amavisd...amavisd is already running.
Starting freshclam...done.

Starting snmp...Done.
Starting spell...Done.
Starting mta...Done.

zmcontrol status reports all running.

Any Ideas?

I also have an identical setup on some different hardware that starts ok...

failing hardware is 1.2Ghz, 512MB, 160HDD
working hardware 1.6Ghz, 1GB, 80HDD

Thx in advance.
