SQL*net V2 problem on AIX 3.2.5

We have upgraded to AIX 3.2.5 recently, and I noticed the following when starting the listener:

Failed to contact: (ADDRESS=(PROTOCOL=tcp)(HOST=venus)(PORT=1600)) TNS-12537: TNS:connection closed

However each base seems to be listened OK (i.e the listener is listening on every base).
What is more surprising is that the last line indicate that "The command completed successfully", and we have successfully accessed different databases from each others... Just as if there was no problem at all!
However I don't like error messages, and I'd rather know why I get this one ;>)

If someone can share some light on this... (by the way I forgot to mention that I relinked the listener).

Thanks in advance

Philippe
