[Bacula-users] copy-job failed on big jobs (other backups use the source

Hi,
I try to use copy-jobs with an neo200s (2 drives,with logical partition:
2 jukeboxes with one drive each).
Bacula is version 5.2.10.
If I run an copyjob with 4.8 TB the job fails during volume-change on
the normal (source) backup-jukebox.
Both jobs failed at the same time (2:00):

The drive has "Maximum Concurrent Jobs = 15" because of multible backup
jobs (sequential due spool = yes).
If I must change the Concurrent Jobs to 1, I guess I run in trouble
during normal backup (backup-window).

But why don't prevent the copy-job to using the source-jukebox for other
jobs??

Any hints??
