A storage mechanism has already been configured for this application

NHibernateSession.Init() or InitStorage() is being called more than once. You're probably calling it every request, it's supposed to be called only once at startup.

In an old application I have to maintain, this happened when the application start had issues. So I just had to recycle the application pool in IIS.

Try to add this line before calling NHibernateSession.Init() to clear any previous initiation.

try{ NHibernateSession.Reset(); } catch { }
