Belatedly - I would only expect you to see any issues if you grab a database connection in a BEGIN block or similar. If you're using Dancer::Plugin::Database, though, you don't need to worry as it's designed to be fork and thread-safe for you. Either way, connections established at run-time should be fine even if you use Starman's --preload-app option. _______________________________________________ dancer-users mailing list [email protected] http://lists.preshweb.co.uk/mailman/listinfo/dancer-users
