Rails - Oct 2006 - Login Engine, user object "marshal data too short"?

This suddenly started happening to my app today.  No code changes, so I
expect that this has something to do with a server change.

I''m using Login Engine and ActiveRecord sessions.  LE stores the whole
user object in the session, then pulls it out as needed with
UserController#current_user.

Out of the blue today this starts failing with the infamous
"you''re
serializing AR objects into the db so you''re getting a
''marshal data
too short'' error".  No code has changed in this app in weeks and
suddenly I''m getting this error.

I can clear all sessions from the DB, do something to create a session
and store a user, then hit another page that pulls the user out of the
DB and I get a Application Error with the log saying "marshal data too
short."

Thoughts?

thx,

If you are using ActiveRecord session store, you may need to change the 
type of your :data column in the :sessions table.  You can do this by 
creating a migration that ups the :limit on the :data column, like so:


def self.up
  change_column :sessions, :data, :text, { :limit => 1.megabyte }
end
