Are you using Windows?  I expect so.

The problem is not with omniORB, it is with Windows' interpretation of
the SO_REUSEADDR socket option. omniORB binds using that option so that
if a server crashes it is immediately able to rebind to the same
address. Unfortunately, Windows allows a process to bind to an address,
even if another process is still using it. There's no way to avoid it
other than not specifying SO_REUSEADDR, but then people would be
complaining that their servers fail to start immediately after a
previous run stopped.

Unix platforms correctly fail to allow you to bind if another process is
already bound.

Cheers,

Duncan.
