If MONITORD daemon (responsible for hardware monitoring) is currently not running for some reason, then CONFD daemon (responsible for Gaia Database and Gaia Configuration) is incorrectly restarted when working with "Hardware Health" page.
When CONFD daemon is starting, by design, it will restart any currently running ROUTED daemons (by sending a TERM signal). It is done to avoid issues with Clish if ROUTED has been running prior to CONFD (issues like returning invalid results for routing-related commands like "show route
").
