Hello,

I know people have probably had success with daemons, however, I am  
running into issues. A simple script to daemonize another script fails  
w/

> ./daemonize.rb run  
> /usr/local/jruby-1.1.4/lib/ruby/gems/1.8/gems/daemons-1.0.10/lib/daemons/daemonize.rb:122:in  
> `each\_object’: ObjectSpace is disabled; each\_object will only work with  
> Class, pass +O to enable (RuntimeError)

> cat daemonize.rb  
> #!/usr/bin/env ruby

require ‘rubygems’  
require ‘daemons’

Daemons.run(‘scaleMatrix.rb’)

# end

> 

I am far from an expert on Ruby so I must be dong something wrong. Any  
suggestions?
