Logged in Administrator List Builds Up when Idle-timeout Set to Never

Issue

With the idle timeout set to never for the admins of the firewall, if a user closes the webui-session/cli session to the firewall abruptly with out logging out, that user will show up in the logged in admins list in the dashboard of the firewall.

The list will keep building up over time as per the screenshot below:

Workaround

Manually clearing the list of logged in administrator will help prevent issues. See the following document:
How to Clear All Existing Admin Sessions

Resolution

Configure the timeout to a value large enough not to be intrusive (24 hours for example).
