How do you enable debug mode on a Zimbra server?
To enable debug mode, stop the Zimbra service with 'zmcontrol stop', replace the zmmailboxdmgr script with the unrestricted version, add JVM debug options to mailboxd_java_options using zmlocalconfig, disable the firewall with 'ufw disable', and restart the service. The debug options include -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:8000.
