I've ran into a problem at one of my clients recently. They are running 5.05 NE. Their last 2 full backups have hung (leaving that user's mailbox in maintenance mode) and despite aborting them in the GUI and the command line, they will not stop. The only way to stop them is to zmcontrol stop then zmcontrol start.
Anybody ran into this problem? Any solutions? If not I will open a ticket with Zimbra support.
