[Kea-users] dhcp4 server stops responding to a device

Hi Gavin,

    "loggers": [

    {
        "name": "kea-dhcp4",
        "output_options": [
            {
                "output": "/var/log/kea-dhcp4.log"
            }
        ],
        "severity": "DEBUG",
        "debuglevel": 99
    }
  ]

I would start by setting debug level to 99 temporarily as shown above.
This will produce vastly more output that can be used to diagnose this
device.  Also, you will get a complete log of packets received and
sent in the dhcp4.packets logger.  If possible, isolate the logs of
this device by collecting logs while only it is attempting DHCP.  This
should help as you should be able to see all of the details of the
entire process.  Please feel free to post the resulting logs of the
device here, as well.

Thank you,
Darren Ankney
