Are you using a pool/counter to manage started jobs?  You should, and
set an upper limit which when reached will through an exception
indicating that the job can't be started.  This should keep too many
jobs from starting.  If the controlling factor goes beyond count, then
you might put in some monitoring access to those factors, and then
access those factors before starting a job to 'count' the appropriate
things.

Also, you could also include monitors/barriers that must be passed which
take 'the size of things' into account so that jobs which are producing
output of some large amount are throttled based on that output rate.
