TNS error

Hello,
I am running 10G xe on windows 2003 server. Everything seems to work pretty smoothly for a few hours and then it bombs. The listener.log file shows this error:

TNS-12516: TNS:listener could not find available handler with matching protocol stack

There are some things in this log that I wonder about. In the piece of the log below you can see that the port number is incremented in every entry in the listener.log. Is this normal? Does this mean that my app is not closing connections? Any help would be greatly appreciated.

what is the status of the listener at this point (plus xe questions are best handled on the xe forum on otn)

It is still running if that is what you mean?
