Clean up abandoned Resque workers.

Prune Resque Workers

There is an issue related to running Resque on Heroku and Resque's ability to clean it's state information for workers. This is mostly a cosmetic issue however we got to a point where the Resque Dashboard would timeout because it was trying to display hundreds of workers it thought were sitll running.

This is a heavy handed approach to cleaning up. We are finding any worker that was stared longer than a day ago and manually calling the unregister method. Be advised this will throw DirtyExit errors.

prune_abandoned_resque_workers.rb

# heroku run console -a appname

days_ago = 1

Resque.workers.select { |w| Date.parse(w.started) < (Date.today - days_ago) }.each { |w| w.unregister_worker }
