Hi Don, My first thought is that something accidentally changed with the lease storage resulting in Kea having no access to the previously leased address records when it was restarted. That is just speculation, however. If you can provide the configuration before and after the change, and some logs surrounding this time period, something might be revealed. Please be sure and redact any sensitive information. Also, the latest stable Stork is 2.0.1 and the latest stable Kea is 2.6.2. You may want to make plans to upgrade.
