[Networker] Networker using only one volume/device at the time, why?

We are using NetWorker version 7.4.4.Build.634, it is running on Solaris 9, has 
one adv_file device with mounted volume from Default pool and we have one 
storage node with 2 adv_file devices with mounted volumes from Default pool.

Lately I noticed Networker is dragging its feet and backup continues into 
working hours so I investigated a bit and concluded that Networker is not using 
all (adv_file) devices/volumes from Default pool. For example, if it starts 
backup from some group it picks volume/device from Default pool. In the 
meantime, another group starts which requests volume/device from Default pool. 
In Default pool we have three volumes/devices available, but instead picking 
one of them Networker repeatedly generates infos/alerts:

backup-sun nsrd media info&#58; Suggest manually labeling a new writable volume 
for pool 'Default' 
backup-sun nsrd media request critical&#58; Waiting for 1 writable volumes to 
backup pool 'Default' disk or tape on backup-sun 
backup-sun nsrd media critical event&#58; Waiting for 1 writable volumes to 
backup pool 'Default' disk&#40;s&#41; or tape&#40;s&#41; on backup-sun 
backup-sun nsrd media request critical&#58; Waiting for 2 writable volumes to 
backup pool 'Default' disk or tape on backup-sun 
backup-sun nsrd media event cleared&#58; Waiting for 1 writable volumes to 
backup pool 'Default' disk&#40;s&#41; or tape&#40;s&#41; on backup-sun 
backup-sun nsrd media critical event&#58; Waiting for 2 writable volumes to 
backup pool 'Default' disk&#40;s&#41; or tape&#40;s&#41; on backup-sun
 
I think Networker should, after reaching target session for one device in the 
pool, pick next available device in the pool and so on. But it doesn't.

Is there a way to check and correct this?
