Question

I am getting the folloinwg error from NHibernate:

System.ObjectDisposedException: Session is closed! Object name: 'ISession'.
   at NHibernate.Impl.AbstractSessionImpl.ErrorIfClosed()
   at NHibernate.Impl.AbstractSessionImpl.CheckAndUpdateSessionStatus()
   at NHibernate.Impl.SessionImpl.FireSave(SaveOrUpdateEvent event)
   at NHibernate.Impl.SessionImpl.Save(Object obj)

I am using NHibernate in .net windows service.
I am not able to trace the excact problem for the exception. This exception occurs very often.
Any one can help me on this to fix this exception?

As the error says – it looks like you are trying to save an object when your ISession is closed. Are you sure you are opening it? Or perhaps it is being closed prematurely?

Update:
Have you checked the NHibernate Logs?
