The _all_ deamons involved is important.

AFAIK is it a "keep alive" signal, which is needed when there
is no data transfer. That "idle" occurs shortly afther job start.
It is when the file deamon is searching / collecting the files
that the bacula-dir requested.

No, it comes only in action during a job's idle time.
Heartbeat is silent when there no "interaction" with a bacula-fd.

Could be. I imagine that there _could be_ a minimal (usefull) interval,
say twenty seconds. That 20 is a value I made up to illustrate
why the heartbeat isn't visible every five seconds by Wireshark.

In our Bacula configuration did the addition 'Heartbeat Interval = 60'
solve time out issues. I had no need to sniff them.
