Description (partial)

Symptom:
If High Availabitity Persistent Chat is enabled and a Subcluster is in Failed Over/Backup, rebooting the Subcluster in that state may lead to a situation, when one of nodes has tcaliases for both nodes in its tc-1.xml config, even though the Subcluster has been restored to Norma/NorIf High Availabitity Persistent Chat is enabled and a Subcluster is in Failed Over/Backup, rebooting the Subcluster in that state may lead to a situation, when one of nodes has tcaliases for both nodes in its tc-1.xml config, even though the Subcluster has been restored to Norma/Normal state already.
That in turn may cause some PChat rooms to be duplicated at non-primary node and eventually be deleted from External DB after timeout.
