Subject: Problem with Ruby Multithreading

Hello Guys,

I am trying to use threads in my RoR app.
But unfortunately I came across a very strange issue.
I am unable to use "finders" within my thread to read data from my
database.
In addition to this, the Thread does not allow me to create any new
object inside the Thread.

Eg:

class TagsController < ApplicationController

def some_method

begin
  Thread.new do
   new_user = User.new
  end
rescue
  p $!
end

end

end

Throws an exception saying
"#<ArgumentError: A copy of TagsController has been removed from the
module tree but is still active!>"

Could somebody guide me where am I going wrong.

Thanks & Regards,

Neha Gupta
