Usually there is no need to restart the qmaster, as all changes are live in the
running process.
Was the number lowered after all the jobs started already, which would imply to
wait until it drained to the lower value?

And the same PE is attached in the same queues to the same set of machines?
Often the changes are limited to adding the PE to a single queue and/or combine
stes of hosts to a hostgroup to have again a single assignment and not listing
all machines in the queue's definition.
