One of the problems with logging configuration is that until you
successfully configure the server it can't really use the log file
location specified in the Kea configuration file. Instead it will use
default locations.
The following section of the Kea User's Guide:
https://jenkins.isc.org/job/Kea_doc/guide/kea-guide.html#logging-during-startup
describes how to influence where the default logging goes. This may help
you determine why the server is not starting. The location of the
default log file being used before the server configures is
prefix/var/kea/kea.log, where prefix is where Kea server is installed.
After the server is started and configured successfully, the logging
should go to the locations specified in the Kea config files.
