Currently if you restart condor while the aggregator is running, condor will forget about all of the provider classads the aggregator initially told it about. On a condor restart, we need to kick the aggregator to ask for these classads again.
Luckily, on bootup condor has a mechanism to "phone-home" that we can hijack. Instead of phoning home, we have condor phone this condor_refreshd daemon, which then re-advertises all of the classads. With this in place, and the appropriate config in condor_config.local, we can restart the aggregator and condor independently and be sure they always know about each other's classads.
