[Touch-packages] [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.

[Touch-packages] [Bug 1872106] Re: isc-dhcp-server crashing constantly [Ubuntu 20.04]
I'm also trying to get isc-dhcp-server running on ubuntu 20.04 with dhcp-failover. I'm using a rpi 3b+ and a kvm vm for failover. Both were running fine with raspbian (rpi) and debian 9 (kvm vm). Now both are running ubuntu 20.04 and isc-dhcp-server will constantly fail (same error as mentioned in previous comments). -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to isc-dhcp in Ubuntu. https://bugs.launchpad.net/bugs/1872106 Title: isc-dhcp-server crashing constantly [Ubuntu 20.04] Status in isc-dhcp package in Ubuntu: Confirmed Bug description: isc-dhcp-server crashing constantly (sometimes within seconds or minutes, sometimes within hours) with the following error messages: Apr 10 17:45:25 xxx dhcpd[140823]: Server starting service.

Happens to me as well. Running Ubuntu 20.04 with package isc-dhcp-server 4.4.1-2.1ubuntu5 I am trying to setup failover pair between RaspberryPi4 and Hyper-V VM.

[Touch-packages] [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.
