Session logout Problem -- db sessions

On the cookie size limit, I'm afraid this isn't exactly true if you are using the CI session implementation and storing in the database. CI by default still stuffs session info in the cookie even if it is in the database too, so getting it too big can still cause issues - but I don't think that's what is going on here.

I would recommend you try setting CI to use a database to store the session simply so you can keep track of it. Then when a person logs in you can see what data the session has (database id number, variable content, etc), then when you force a logout you can see what happened to sessions in the database.

It would be very helpful to know what happens - does the session still exist and the data gets lost, or is the old session there and the logged out person now has a fresh session?

That would narrow down the theoretical range of problems.
