I'm assuming you invoke some particular .rb file to start your whole
rails app?  (Or, if not, that you can at least find some .rb file
on your system that is the main .rb file that starts up rails?)

If you haven't already, I'd suggest trying what Caleb suggested:
putting: BasicSocket.do_not_reverse_lookup = true
at the top of that file.

If that doesn't help, I'd suggest trying: require "resolv-replace"
at the top of that .rb file.

If that doesn't help, I'd suggest adding the trace code I
posted yesterday to the top of that .rb file.

With the lengthy delays you've been experiencing, I'd imagine
the trace code may provide some confirmation as to exactly what
code is being executed at the time of the pause.


Hope this helps,

Bill
