[Kea-users] Dhcp6 crash with config-reload command v2.6.3

Hi All,

I’ve been experiencing an issue with kea-dhcp6 (4 doesn’t seem affected) where when I issue a config-reload command directly to the dhcp6 socket, the server crashes.

Looking at the backtrace it seems to be related to the lease management – I’m using memfile – and maybe some cleanup that is done as part of the reload?

Has anyone experienced something similar?

Note that the config file loads fine when starting the server.

Here’s a backtrace and a few more things from the coredump if it helps: https://gist.github.com/DiogoAndre/aa8c144329424b431b755711d7a96606

Thanks,
– Diogo
