Sorry, I jumped back into the conversation without seeing the
follow-ups, so my last post was a bit redundant.
But just to reiterate what Dimitri said earlier: putting the daemonize
call before the listener is probably not enough. You also have to make
sure that you do not open any IOs (files, etc.) until after the
daemonize call. For example, I had a log file open before daemonize and
ended up with 'IOError closed stream'
I do think though that there's probably some way to fix this on the
mongrel side. WEBRick seems to be able to daemonize itself without any
IO voodoo.
