Cisco DNCS System Release 2.8.1 3.8.1 4.3.1 User Guide

This section describes how to tear down sessions for either of the following reasons:



You need to delete a QAM modulator that carries content.

Note: Before deleting a QAM modulator that carries content, first tear down sessions associated with
the modulator. Deleting a modulator without first tearing down its related sessions can degrade system
performance. Performance can degrade because the DNCS uses its resources to attempt to associate
sessions with a modulator that no longer exists. These sessions are called orphaned sessions.



You need to tear down and restart an unlisted, active session in order to correct it.
