Very odd.  When you say that you do a condor_restart on louie, what 
daemons are running on the machine in question?  Are you restarting the 
schedd, or is it just the collector and negotiator?

In the schedd logs, you should see statements about the "flock level".  
Can you please check what this is doing during the time when flocking is 
not working?
