The Monitoring service is not available

If your Coldfusion 10 service refuses to start and you see something like in your /Applications/ColdFusion10/cfusion/logs/start.log

Feb 21, 2012 11:58:54 AM Error [pool-2-thread-1] - Unable to initialise Monitoring service: coldfusion.server.ServiceException: Address already in use

just trash the /Applications/ColdFusion10/cfusion/lib/neo-monitoring.xml and restart your Coldfusion 10 instance:

sudo /Applications/ColdFusion10/cfusion/bin/coldfusion restart

Coldfusion will create a new neo-monitoring.xml file for you.
