Stephane, It appears that we have found the problem, which even OTS missed. Like = I stated in the original message, I had built a new database instance = over the weekend. Now, how many of you copy from one instance to = another when creating new, especially things like init.ora files? Well, = I did & I missed a parameter called "instance_name". Therefore I ended = up with two instances having the same "name". The default is the SID, = which is older version behavior & consequently I never had it in an = init.ora file. Well in 9i it's there & I missed it. Thankfully it's a = changeable parameter, just needs an instance restart. Problem fixed.

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.
