Re: [Condor-users] memory leak in Condor 7.4.2 schedd ???



In that case, you create a stand alone collector, that's no tied to the pool, then you can use the pools off-line machine class ad log file to load all the offline machines into the stand alone collector.  After that, just use condor_advertise to send new machine ads to the collector, and watch how it responds. 

The original class ad log file should be easy enough to find, it should reside where OFFLINE_LOG points to.
