OK, so both jobs are running on the FD. Concurrently.

Thus, the problem, must be the SD.  Let's look below..

NOTE: You mention DIR, but 'waiting for a volume' is an SD thing, not a 
DIR thing.
That is, the SD is waiting for a new volume.

Let's assume you are backing up to disk.

Is the SD set to automatically create/label Volumes?

The output from status storage would be useful here.  As would the 
versions
of Bacula you are using (SD, DIR, FD).
