If the client is present, the DIR starts the job, else he waits for him during a time specified in the Client ressource in the bacula-dir.conf (this parameter is named "WaitTimer"). He checks if the client is connected at each interval of a time (attribute "PresenceTimer" in bacula-dir.conf). If the client never connect himself during the "WaitTimer" time, the job is marked as "JSAutomaticallyCanceled" in the Catalog. "JSAutomaticallyCanceled" is a new parameter defined in jcr.h and it means that the job is canceled because the File daemon has never been connected.

The parameter MaxClientsPresence defined in Director ressource in bacula-dir.conf decide how many File Daemons the DIR can listen simultaneously.

A side note:

Port 9104 should be registered.  The world knows that ports 9101, 9102, 
and 9103 are used for Bacula.  ;)
