Well I thought I was implementing the this properly. But your statement saying "This can happen when storing a reference in a singleton" might be what is happening.
I've placed my session implementation here: http://www.keelio.com/session.zip There are two .cs files in there. My manager objects call NHibernateSessionManager.Instance.Session and stores it locally as a protected INHibernateSession variable. NHibernateSessionManager.Instance.Session is stored as a static property: public static INHibernateSessionManager Instance I get an instance of my manager many times throughout the application, which I believe just pulls the ISession object out of httpcontext.current.items. Perhaps if there is a good example of this out there I can narrow into my issue.
