Facebooker talk - Nov 2008 - Facebooker config goes away in production

Hi all,

I''ve been having some issues with facebooker in production.  The server
is a CentOs box with thin v1.0.0, ruby v1.8.6-287 & frozen rails 2.1.2.
I just updated to the latest rev of facebooker this morning (for
action_links, nice), but we''ve been pretty up to date even before now.

Is anyone else deployed on a similar setup?

The bug is facebooker''s configuration goes away.  This usually happens
after a few hours of being up.  The only theory I have right now is that
thin is reloading classes after they get "stale" and overwriting
configuration data.  It looks like the "Facebooker" constant itself
becomes a hash (see the last exception below).

Sometimes this results in a literal config missing error:

-------------

vendor/plugins/facebooker/lib/facebooker/session.rb, line 529
vendor/plugins/facebooker/lib/facebooker/session.rb:529:in

and sometimes in a variety of other exceptions:

------------

vendor/plugins/facebooker/lib/facebooker.rb, line 102

vendor/plugins/facebooker/lib/facebooker/rails/controller.rb:115:in

Mike or David, does it make sense that reloading the facebooker classes
would blow away the config?
