[Bug 1872106] Re: isc-dhcp-server crashing constantly [Ubuntu 20.04]
Hi Jorge. How to get a crash report? I simply start the service and it dies after some seconds. Nothing in the dhcpd log is indicating a crash. The process is simply gone.

This looks like a duplicate of bug 1872118 which is purportedly fixed with a change to bind9-libs. However, I don't see the relationship between bind9-libs and isc-dhcp.

@mm - that probably isn't the issue, but you can adjust
/etc/apparmor.d/local/usr.sbin.dhcpd to have:
@{PROC}/sys/net/ipv4/ip_local_port_range r,
and then do: sudo apparmor_parser -r /etc/apparmor.d/usr.sbin.dhcpd #
yes, without local/

[Bug 1872106] Re: isc-dhcp-server crashing constantly [Ubuntu 20.04]
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.
