I have some thing similar
I have a pair of DHCP serevrs running in a cluster on ubuntu 20.04, All worked perfectly until recently, when they started stopping with code=killed, status=6/ABRT. This is being fixed by https://bugs.launchpad.net/bugs/1870729 However now one stops after a few hours with the following errors. One can stay on line but not both. Syslog shows Apr 10 17:20:15 dhcp-primary sh[6828]: ../../../../lib/isc/unix/socket.c:3361: INSIST(!sock->pending_send) failed, back trace Apr 10 17:20:15 dhcp-primary sh[6828]: #0 0x7fbe78702a4a in ??
