Hello everyone!
It's a very delicate problem。
when using the Nhibernate at the server terminal of .net remoting,
every time the momery of creating the session server will decrease,
after completing the execution of session,we should shut down it in time,but the momery won't be relasaed.if the running time is very long,all the server memory will be run out.

Usually this means objects referencing your ISession (or objects referencing you objects referencing ISession, etc) are not released.

We had similar problem with asp.net application once. We had used static event (very bad idea) and every time a page handling this event was loaded it happily stayed in memory until end of time. Well, server lifetime.

Frequently creating SessionFactory
will cause the memory to leak!!!!!!

You should create the SessionFactory only once (at the loading of your server application)
