OpenVMS 7.3-2, Python 2.3.5, no idea about IP stack version.

I don't have any small case lying around (I can't reproduce it myself
because I lack access to an openVMS machine) but I think you should
be able to reproduce it by slightly altering one of the socket examples
that comes with Python. Just add the MSG_WAITALL to the recv() call:
something = sock.recv(somesize, socket.MSG_WAITALL)
and you should see it crash with a socket exception.
Mail me offline if you still need running example code (that I think
would expose the problem).

I don't have anything to do with HP... the person that reported the
problem to me has, however. He's already aware of the problem.

How can I detect that I'm running on OpenVMS?
