Hi All,

This might seems to be a silly post for all the pros out there but can  
anyone please try to answer my question?

I have installed backgroundrb 1.1 version on my RH Linux system.  
And now I don’t see any MiddleMan class in any of the backgroundrb.rb  
files under $RAILS\_ROOT/vendor/plugins/backgroundrb/  
lib/ and  
script/

I have totally followed the steps from :  
[http://gnufied.org/2008/05/21/bleeding-edge-version-of-backgroundrb-for-better-memory-usage/](http://gnufied.org/2008/05/21/bleeding-edge-version-of-backgroundrb-for-better-memory-usage/)

and installed the chronic packets as mentioned @  
[http://backgroundrb.gnufied.org/index.html](http://backgroundrb.gnufied.org/index.html)

When I run the tasks from my ROR framework, I get the following error:  
undefined method `[]’ for #

This error is caused from the controller file where I am creating a new  
MiddleMan thread.

if MiddleMan[server] == nil  
puts “creating thread #{server} at #{Time.now}”  
end
