Ran a upgrade this morning and all went well!! Installed some new RAm into the Zimbra server (8Gb) and since the shutdown I am unable to login to my webmail or admin interface.

zmcontrol status shows:

Host mail.xxxx.com.au
antispam Running
antivirus Running
imapproxy Running
ldap Running
logger Running
mailbox Stopped
zmmailboxdctl is not running
mta Running
snmp Running
spell Running
stats Running

A stop & start has the same effect.

/var/log/zimbra.log states:

Jul 7 18:56:07 mail zmmailboxdmgr[11792]: status requested
Jul 7 18:56:07 mail zmmailboxdmgr[11792]: stale pid 10278 found in /opt/zimbra/log/zmmailboxd_manager.pid: No such process
Jul 7 18:56:07 mail zmmailboxdmgr[11792]: assuming no other instance is running
Jul 7 18:56:07 mail zmmailboxdmgr[11792]: file /opt/zimbra/log/zmmailboxd.pid does not exist
Jul 7 18:56:07 mail zmmailboxdmgr[11792]: assuming no other instance is running
Jul 7 18:56:07 mail zmmailboxdmgr[11792]: no manager process is running

Thanks in Advance.
