I just moved primary dns and dhcp from 16.04.6 LTS to 20.04 LTS and also observe this behavior.
Primary is isc-dhcp-server 4.4.1-2.1ubuntu5 amd64. Crashes regularly. Secondary is isc-dhcp-server 4.3.5-3+deb9 armhf which runs fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872118 Title: DHCP Cluster crashes after a few hours To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/isc-dhcp/+bug/1872118/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
