Bug description:
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

However now one stops after a few hours with the following errors. One
can stay on line but not both.
