Was that job run supposed to use data spooling ? I ask because I have
SpoolData = yes in job definitions (and that automatically enables
SpoolAttributes = yes, btw), and I get messages like this:

FYI: fileserver is a virtual machine on a different host.
HP LTO-1 drive, spool area and bacula database are on the same machine
(postgres, btw).
