.NET farmework 2.0 
MS Sql Server 2005 

This issues is described on the forum: 
http://forum.hibernate.org/viewtopic.php?t=952999&postdays=0&postorder=asc&start=15 

That's how I create my session factory: 
static DataStore() 
{ 
sessionFactory = new Configuration().Configure().BuildSessionFactory(); 
} 

That's how I create and use my session object 

public void UpdateX(X newX,) 
{ 
AssertNotNull(newMessage); 

using (ISession session = sessionFactory.OpenSession()) 
{ 
using (ITransaction transaction = session.BeginTransaction(IsolationLevel.RepeatableRead)) 
{ 
// some statements 

transaction.Commit(); 
} 
} 
} 

Now when I call UpdateX using two concurrent threads I'm getting this error:
