Hello Palica:

Can you provide a core file or backtrace?  Your issue may or may not be
the same as Juan's problem. His crash seems to be occurring during host
reservation look up.  Are you using MySQL to store host reservations? 
The more information you can provide the better.  If any of it is
sensitive you can email it to me directly.

What the Kea should do, when DB connectivity loss is detected, is to
gracefully exit with an error.  We have connectivity recovery slated for
an upcoming release.
