My case is not quite the same, but as I recall, I wasn’t able to make  
\*/1 work.

I use

:trigger\_args: 0 \* \* \* \* \* \*

To fire the worker once a minute.

I’m also not certain that :worker\_method works. I use:

:worker\_method: :do\_work

And call the “real” method from do\_work.

I don’t do this, just set up the config files and  
(nohup) script/backgroundrb start

(The nohup is required if starting it remotely, e.g., from capistrano,  
to keep it from quitting when you exit the shell you started it from.)

I hope this helps. I’ve been using backgroundrb happily for several  
months for DB backup, session expiration, and periodic emails.

I can’t seem to get backgrounDRb up and running.

Here is my “backgroundrb.yml” file \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*  
autostart:  
1:  
job\_key: mailing  
class: mailman\_worker  
Here is “mailman\_worker.rb” \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*  
class MailmanWorker \< BackgrounDRb::Rails

repeat\_every 5.minutes  
first\_run Time.now

def do\_work(args)  
## This will send all the emails in the queued\_mails table  
script/runner ‘MailQueue.process’ -e development #change  
“production” to “development” or vice versa depending on what you’re  
doing  
kill()  
end

end

It never seems to run. What do I need to do to get it to start up  
automatically, and then run every 5 minutes?
