The replication actually isn't going down.  Just the had and negotiator.

I tested that on condor-7.8.8-0.1, it still takes about 6 minutes till the negotiator and HAD starts again.

# cat NegotiatorLog

# cat HADLog

Comment 6 Robert Rati 2013-01-09 15:47:51 EST
The issue was the the negotiator and had went down and never came back up.  Since the had and negotiator daemons are restarting, it seems like things are working as expected.  I suspect the reason it is taking ~6 minutes for the had to restart is because MASTER_HAD_BACKOFF_CONSTANT = 360 (6 minutes) in the HACentralManager configuration.
