Charlie,

	Sounded interesting so I gave this a try on our test environment, with 
the following config:

Host *
  ControlMaster auto
  ControlPath ~/.ssh/master-%r@%h:%p

	Initially, all looked well, but then we started to see these:

Remote command execution failed: Control socket 
connect(/var/log/nagios/.ssh/master-root at 192.168.100.100:22): Connection 
refused

	So you see this as well in your environment?

Best Regards,
Camron
