perhaps that used to be the case, but now there _is_ a max sessions setting for
each device which NW does abide by

Max target sessions is not absolute, server parallelism is. If for
example, you only have one appendable tape for the given pool, and you
set max sessions on all affected devices to, say 8, but your running
group(s) consist of 50 save sets, then there's nothing to prevent NW
from upping the sessions from 8 to 10 or 12, maybe even higher. I've
seen NW do this any number of times. Typically, NW will try to down the
numbers back to the max sessions as soon as it can, but it might take a
while. Of course, it does abide by this if it has another volume it can
load, and then once that's maxed out if it has another, etc., etc. but
if it needs more and there are no more tapes and/or available devices
then it can and will up the sessions on one or more as necessary.
