As nobody took a shot at this, While you are ok on memory and CPU - have you looked at your other resources? With that many hosts reporting back to a master - I would suspect I/O flooding off your interface...
Just a thought ....

Once I start to get around 2700 hosts hobbit stops updating. Is there a cause for this in hobbit (memory or host limit)? Top shows my system with very little utilization of memory or cpu and all hosts go purple for no updates. I can get hobbit updating again by commenting out hosts and restarting it but I still have roughly another fifteen hundred hosts to enter. I have been adding the hosts in slowly in groups of less than two hundred which seems to work better as I was seeing everything go purple at under two thousand hosts before.
