Dick,

   I don't think that it's a matter of number of instances, I have known
a development box with over 40 ...
I don't see anything shocking in your listener.ora file. I infer,
possibly wrongly, from your having prespawned processes that you are
using dedicated servers. Since it starts properly, it means that the
listener connects a new session to the proper pre-spawned process. It
should be interesting to check whether you have the same behaviour when
you have MORE sessions than prespawned processes - or trying without any
prespawned process.
Intuitively, I'd rather think of a problem on the client side - some
corruption bringing the client to talk to the wrong port. Have you tried
tracing ?
