So you're seeing a HUP signal for some reason, so that's something you
have to track down. But, HUP does a "reload" of Rails, which tends to
not work so well. If you get a HUP and the server stops working after
that, then the only thing you can do is not send the process HUP
Is someone doing a capistrano deployment that is doing a reload rather
than a restart?
