Active Record Sessions only work on localhost

Hi I was wondering if anyone else was having this problem or might know why its happening.

I basically need to use AR sessions instead of the default pstore for sessions so I did the rake db:sessions:create to get the migrate file and then the rake db:migrate to create the session table.

Also uncommented the below line in environment.rb

config.action_controller.session_store = :active_record_store

started the server and everything works as advertised on localhost (winxp, rails 1.2.3, ruby 1.8.6)

But when i did the same for my production machine (ubuntu, rails 1.2.3, ruby 1.8.6) the sessions dont seem to work. First thing i noticed was that for each session, 4-5 entries were created in the sessions table while on my local machine only 1 entry was created. Can't find any error messages in the logs either.

Any help ideas or anything is much appreciated, I couldn't find any help anywhere else.

Thanks in advance, Jarrold
