When using the shutdown command via the API, kea-ctrl-agent does not
segfault:
# kea-shell --auth-user kea-api --auth-password $(cat
/etc/kea/kea-api-password) --host localhost shutdown
[ { "result": 0, "text": "Control Agent is shutting down" } ]
I had the server running inside gdb:
(...)
DEBUG CTRL_AGENT_RUN_EXIT application is exiting the event loop
INFO DCTL_SHUTDOWN Control-agent has shut down, pid: 460849, version: 2.4.1
[Thread 0x7ffff4fcf0e0 (LWP 460854) exited]

(gdb)
So, normal exit. But when reacting to the TERM signal, it segfaults:
Thread 1 "kea-ctrl-agent" received signal SIGTERM, Terminated.
