Hi Diogo,

That backtrace doesn't look particularly useful because no symbols
were found.  Kea's logs would probably be far more useful in this
case.  it would have some message indicating why it is exiting.  Here
is one example of a problem you could be encountering:
https://gitlab.isc.org/isc-projects/kea/-/issues/3986 but without log
messages, it is just guessing.

Thank you,
Darren Ankney
