After upgrade some services don't start because of wrong permissions on log files.
Trying to restart server with zmcontrol gives errors
Code:

Running zmfixperms is useless.
Changing permissions to zimbra solves it for me.

Code:
dario@smtp:/cd /opt/zimbra/log
darioj@smtp:/opt/zimbra/log$ sudo chown zimbra:zimbra freshclam.log clamd.log httpd_error.log httpd_access.log mailbox.log mysql_error.log myslow.log zmmtaconfig.log
Hope this is the only problem with this upgrade.
