Hi Simon, The passenger worker processes are and have been running since a few days ago (quick "ps" shows they have all been alive at least 3 days).
Production.rb has: ----------------------------- config.cache_classes = true config.action_controller.consider_all_requests_local = false config.action_controller.perform_caching = true config.action_view.cache_template_loading = true Apart from that no "caches_page" or "caches_action" directives are used in any controllers or anywhere else in the rails app etc..
