[Kea-users] Unable to re-allocate address

[Gordon Ross]

My configuration is very simple. There are no hooks, no HA, no multi-threading, no fancy commands.

Postgres version is 12.7

    Gordon,

    Thanks for posting your issue to the Kea users list. I will try to
    replicate your issue tomorrow with the Postgres lease database backend.

    It will be super useful if you send me your Kea configuration file. You
    can sanitize it from any private stuff it may contain. Please send it to
    me privately if it can't be posted to the mail list.

    If it is not possible, please describe the major parts of the
    configuration, e.g. is multi threading on or off, are you using any
    hooks libraries (e.g. lease cmds?), are you sending any commands to Kea
    that can possibly modify the lease information?

    Finally, please provide your Postgres database version.

    Kind Regards,

    Marcin Siodelski
