Here is my setup:
Maximum jobs per client: 4
Storage Unit: Maximum multiplexing per drive: 4
Class:allow multiple data streams

Here it what  I run from client:

#bpbackup -f filelist1
#bpbackup -f filelist2
#bpbackup -f filelist3
#bpbackup -f filelist4

filelist1:
/var
/opt

filelist2:
/home

filelist3:
/oracle

filelist4:
/apps


If I look at server acivity monitor, only one backup is active, all the
other three is queued.
That is not what I want, I want four all to be active.

I also tested start the class from server, multistreaming works, but now
from client

Thanks
