Are you using SplayTime? I had trouble with cfengine clients gobbling 
up all of my servers' connections. Rather than raising the limit I 
found and used SplayTime to spread out the load. We're running cfengine 
every 30 minutes here, so I set SplayTime to 25 minutes in update.conf. 
This gives systems running on the 25th minute an ample five minutes to 
run and release locks:

control:
	!slave.!master::	SplayTime = ( 25 ) # minutes

One other problem I had was with incorrect ethernet duplex settings on 
a couple systems. Their runs weren't finishing within thirty minutes, 
and after a few days the connections were all busied up. It'd be nice 
if cfservd had a maximum connection time limit so I'd get cfengine 
email from the problem system rather than from all systems. Tons of 
warnings is better than no warnings though.

No idea there. I started with 2.0.7p3 this past summer and haven't seen 
that problem.
