Based on the error message, both processes might be trying to use the same
lock file,
/var/run/kea/isc_kea_logger_lockfile
or maybe that directory does not exist, or has wrong permissions.
You need to somehow configure them to use different lock files.
I don't use Kea, so I have no idea how to configure that.
