[Kea-users] "ha_dedicated_ports" warning in Stork

[Marek Hajduczenia]

Hi Darren,

Kea logs did not show any standing issues, at least not that I could find
any indication of problems. A stream of standard notice / warning messages
indicating proper operation of individual Kea nodes.

I did restart the VM hosting Stork functions to finish kernel upgrades and
... everything works right now. Whatever was going on in this case seems to
have been Stork related. I will continue monitoring and see whether the
issue re-appear. Is this the correct mailing list to work through any
Stork-related issues as well?

Marek
