[omniORB] How to get rid of the POA?

[Andreas Bille]

Hello all,
spinning around a little bit, I found no solution to the
(beginners?) problem to peform several run/destroy-cylces with omniORB,
if during such a cycle the POA is resolved.
That is, the second call

'Poa = self.Orb.resolve_initial_references(PoaName)'

in the attached 'test.py'
gives :

<prog>
omniORB: Error: Unable to create an endpoint of this description: 
giop:tcp:localhost:54321
Traceback (most recent call last):
  File "./test.py", line 47, in ?
    sh.shutdown()
  File "./test.py", line 35, in shutdown
    Poa = self.Orb.resolve_initial_references(PoaName)
  File "/usr/lib/python2.3/site-packages/CORBA.py", line 480, in 
resolve_initial_references

omniORB.CORBA.INITIALIZE: Minor: INITIALIZE_TransportError, COMPLETED_NO.
</prog>

I used omniORB-4.0.2/omniORBpy-2.2 over Python-2.3.
Does anybody know a way out?

Greetings,
Andreas Bille
