ActionView::TemplateError (undefined method


I am using following configuration on my production environment:

Rails (2.0.2)
Ruby 1.8.6

I am getting following error after my server runs for some hour (6-8
hr). Also, the problem
goes away once i restart all my mongrels (only to come up in next 6-8
hr :frowning: ).

Following is the trace of error:

ActionView::TemplateError (undefined method `billing_contact' for
#<Domain::ResellerDomain:0x2aaaaea710f8>) on line #55 of domain/
    52: <tr>
    53: <td>

      56: "registrant" => @domain.registrant_contact,
