rufus-scheduler runs scheduler multiple times due

Question

I had setup scheduler in my rails3 projects's /configs/initializers/schedule.rb and it working fine, But it works 2 times and I think it is due to unicorn workers execute schedule at the same time, so it create in my database two records each time. I checked my logic and its ok and enter single record in my local machine.

I checked following but not getting idea how to stop multiple unicorn workers to execute scheduler?
