Yes:
    SpoolData = yes
    SpoolAttributes = yes
    Spool Size = 49807360000

(Also Maximum Volume Bytes = 49807360000 -- these are disk volumes.
And Maximum Network Buffer Size = 65536)

I might try that but I don't believe postgres is the bottleneck.

Looking at the director side, I have Max concurrent jobs = 10 and it
seems only 5 are running (there's more in the queue): 3 from Jan 19th
and 1 from Jan 21st. Is there any kind of scheduling going on that would
starve the job? -- all 5 seem to be spooling...

I might try sticking in an SSD for the spool drive to make sure that's
not the bottleneck.

Well, that's more helpful than bacula-fd manpage: at least it mentions
the trace file. So where do the debug messages go with trace=0: syslog?
And what are the levels? -- 'cause I started bacula-fd with "-d 9" and I
got nothing in /var/log/messages.
