Hi all, I''m running a site on Rails, and since I upgraded from 0.13 to 1.0, I''ve been seeing trouble with instances (via fastcgi) losing their symbol table. After some period of running (several hours), the instance will lose some section of its symbol table. What I mean by that is, I start seeing a bunch of exceptions like undefined constant: xxxxx where xxxxx is one of my models. It''s not limited to AR models, either. The latest: undefined method `init'' for Mysql:Class Restarting the dispatcher fixes the problem for another period of time. This never happened prior to Rails 1.0, and I haven''t seen anything on this list addressing it. It''s a large app, and the source could frankly be anywhere! Any tips on how to find this?
