Yeah, definitely the listener is a good place to start. But, also in 11g
auditing defaults to DB and audits CREATE SESSION, so if it hasn't been
disabled there may be some answers in DBA_AUDIT_SESSION:

 http://docs.oracle.com/cd/B28359_01/server.111/b28320/statviews_3071.htm

Sometimes it's not new sessions that are the cause of the problem, but
rather sessions that are supposed to close are failing to do so.
