rufus cron job not working in Apache/Passenger

问题:

I have a Rails app running on Apache/Passenger. It has a rufus-scheduler cron job that runs in the background and sends out notifications via email.

When I am running the app in development on the WEBrick server, the emails are sent like they are supposed to be sent.

When I start up the app in production on Apache/Passenger, the emails don't get sent. In the production logs it doesn't show any logs for rufus-scheduler.

I'm stuck in this problem. Your help will be appreciated, thank you in advance.

The easiest solution is to set PassengerSpawnMethod to direct. The Phusion Passenger documentation explains why this solves it: http://www.modrails.com/documentation/Users%20guide%20Apache.html#spawning_methods_explained In particular, take a look at section "15.4. Smart spawning gotcha #2: the need to revive threads".
