I see that I am in good company on having this issue after upgrading to 6.0.x. I upgraded from 5.0.16 and also upgraded to 6.0.1. I backed up, made sure there were no zimbra processes were running, and did the upgrade.
Now, I get messages stating
However, netstat shows there is nothing on those ports:
Zimbra server reserving server socket port=110 bindaddr=null ssl=false
Zimbra server reserving server socket port=995 bindaddr=null ssl=true
Total time for which application threads were stopped: 0.5210790 seconds
Fatal error: exception while binding to ports
I also saw in /var/log/zimbra.log that it is looking for zmmailboxd.pid, which does not exist:
[root@merrimac ~]# netstat -pan | grep 110
[root@merrimac ~]# netstat -pan | grep 995
Nothing in /opt/zimbra/log/mailbox.log since 12 Oct.

pid does not exist
And here is my obligatory netstat -pan (zimbra is not running):

I had to disable exim4, since it had been reenabled on upgrade. After that, I did a reinstall of Zimbra, from 6.0.1 to 6.0.1. The only difference is that when I installed the first time, I installed memcached, but uninstalled the package before reinstalling (though it still tries to start it...) I also tried suggestions from some older threads, including removing the zmmailboxd*.pid files and trying to start zmmailboxctld by hand, to no avail.
Suggestion on what is causing my particular issue?
