It looks like you are trying to use one of your models across the  
wire. What classes are involved in this error? Can you show us your  
code in rails and in the worker please? I think you will be able to  
solve this by including DRbUndumpoed in your classes that are  
involved. So if you have a Post model that you need to send across  
the wire to a worker then you will need to add this line to the class  

class Post < AR::Base
   include DRbUndumped


That will fix the DRbUnknown errors for you.
