Interesting... on the processing nodes it's condor_master
udp 0 0 10.178.6.169:55607 10.178.6.5:1980 ESTABLISHED 2758/condor_master
udp 0 0 10.178.6.169:41271 10.178.6.5:1980 ESTABLISHED 2758/condor_master
udp 0 0 10.178.6.169:52919 10.178.6.5:1980 ESTABLISHED 2758/condor_master
udp 0 0 10.178.6.169:55735 10.178.6.5:1980 ESTABLISHED 2758/condor_master
I may try to downgrade condor. It looks like it occurs after about 20 minutes; it's killing my cluster.

Can you say which particular condor process is holding open the ports?
(as root) should show you the process name and pid for each socket.
