If a secondary administration console gets into a non-reporting state, perhaps caused by hardware failure, its configuration needs to be removed from the Primary Administration Console. As long as it is part of the configuration, other Access Manager devices try to contact it.
If you cannot remove it the normal way, which is by running the uninstall script on the Secondary Administration Console, you can remove it using the troubleshooting page.
In the Administration Console, click > > .
In the section, select the failed console, then click .
All references to the secondary administration console are removed from the configuration database.
