Q:

Running resque-scheduler on a web farm

If I'm running a resque cron job to run every hour using resque-scheduler on a web farm of say 2 or 3 web servers... how do I get it so that the job isn't submitted once for each web server? 

A:

Resque-scheduler has a scheduling process that must always be running.  Only one instance of it should be started, on a single machine.
