I'm looking for a similary post with this error, and I found where anybody tell, that check the number of conections server or the Dispatcher, but I don't Know What's Dispatcher?
How do I active the Trace ?
add TRACE_LEVEL_LISTENER = ADMIN
to your listener.ora and restart listener.
You can find trace file under my_directory.
