Is the DAGMAN_MAX_JOBS_SUBMITTED value in a per-DAG config file?  If so, I 
think you could do condor_hold on DAGMan, edit the config file, and then 
condor_release on DAGMan.  I haven't tried this, so I'm not totally sure 
it will work, but I think it should.

Condor_hold on the DAGMan job won't stop any currently-running node jobs, 
so at least you should't lose work that's already in progress.
