   What changed immediately prior?  Any software/firmware updates to Kea 
or OS or libraries or routers or switches or CPE?  Any changes in 
configuration?  Were any Kea API commands being performed around when 
the crash occurred?

   What distribution and release?  What kernel version?

   Please provide the output of "kea-dhcp6 -V" from the server that crashed.

   Please provide a copy the configuration in use at the time of the 
crash.  Redact passwords and the like, of course.

   Have you captured a core dump?  If not, please do so.  If yes, can 
you please provide a backtrace of all threads?

   You can post large text dumps to a site like https://pastebin.com/ if 
that helps.
