mod_c2s: Don't call ondisconnect manually on close, it is now called by net.server. Replace with inline code for destroying the session, and also waiting for a reply </stream:stream> if there is a chance of further data sent by the client. session.send() on a half-closed stream returns false (and does not deliver the data).
