[Kea-users] heartbeat-delay in LB mode and lease updates

Hi!

Looking at the following bit from the Kea ARM


  *   heartbeat-delay - specifies a duration in milliseconds between sending the last heartbeat (or other command sent to the partner) and the next heartbeat. Heartbeats are sent periodically to gather the status of the partner and to verify whether the partner is still operating. The default value of this parameter is 10000 ms.
https://kea.readthedocs.io/en/kea-2.6.2/arm/hooks.html#load-balancing-configuration:~:text=heartbeat%2Ddelay%20%2D%20specifies,is%2010000%20ms.

Would this mean that the servers may not exchange a heartbeat if other commands (like lease updates) are being exchanged within the set heartbeat-delay?

Thanks,

  *   Diogo
