This option explains why the user sessions have not fallen back to the homed nodes after the failed service or server was restored. The Client Re-Login upper limit setting determines how long the Jabber clients will attempt to re-login to their homed nodes after a failover event. If the failed service or server is offline longer than this setting, the Jabber clients will stop trying to re-login and will remain on the backup node until the administrator manually initiates a fallback or recovery. The default value for this setting is 30 minutes, but it can be changed in the Server Recovery Manager Service Parameters. References:
