This is issuing a close on a disconnected transport. So the client
builds a new transport to send the close which of course makes no sense
but that's generic programming for ya. I think your socket is being
clobbered somehow.

You really need to isolate the problem enough so that you can get a
packet capture [1] of the problem happening from connect to disconnect
and not just the part where it issues the close on the dead connection --
the interesting part has already happend by then.

Also, check the Samba logs. It could be that jcifs said or did something
Samba didn't like.

Also, try running the whole ball of wax against a Windows 2000/3 machine.
