When you say "Central Manager" I'm assuming that mean a single machine
running both your condor_negotiatior and condor_collector daemons.
Correct? And that the machine you've submitted these held and running
jobs from, the one running the condor_schedd daemon, is not the same
physical machine. If these assumptions are correct you can safely reboot
the "Central Manager" machine without any adverse impact to running or
queued jobs.

You may wish to consider taking advantage of Condor's high availability
features in the 6.7.x development branch to run a mirror central
manager. This would give you complete redundancy and the ability to
reboot a central manager without halting the assignment of new jobs to
remote execution nodes.
