> hi,
> we use seam/spring/hibernate in our application. We detected a problem that database connections are not released after each request during seam conversations. Then if we have many conversations we can run out of connections.
> Let me explain this issue a little bit more:
> If a conversation starts a session is opened. This session is bound to the conversation and borrows a database connection from the pool.
> After the request the session doesn't have to be closed necessarily, but the session should be disconnected (to release the connection).
> What happens in the code (org.jboss.seam.ioc.spring.SeamManagedSessionFactoryBean) is that the session only is 'marked' as closed. 
> Later seam recognizes that the conversation is still opened and the session will not be closed at the end of the request. The connection is therefore
> not returned to the pool for many requests until the conversation ends.
> For our case we fixed this problem by slightly changing the code of org.jboss.seam.ioc.spring.SeamManagedSessionFactoryBean (see the patch file). We added code to disconnect the session
> greetings fke
