Your traces for GIOP 1.1 and 1.2 both have the same format, where
omniORB says:

and ORBexpress says

> 4749 4f50 0100 0006 0000 0000           GIOP........

which is a GIOP 1.0 MessageError message. It shows that ORBexpress
doesn't support GIOP 1.1 or 1.2.

The trace for GIOP 1.0 is different...

[...]

That shows that omniORB sent the request and ORBexpress just didn't
reply at all. It just left the connection open. Without a timeout
configured in omniORB, it will sit there for ever waiting for a reply
that isn't going to come. You'll have to see if there's any tracing
you can to in ORBexpress to see what it thinks is going on.

Cheers,

Duncan.
