The original primary issue (that pid files were not being written at all) was resolved in isc-dhcp 4.3.3-5ubuntu9. However both isc-dhcp- server & isc-dhcp-server6 systemd units continue to use the same RuntimeDirectory, so that when either service is restarted (eg to reconfigure), the pid file of the other service is lost.
** Summary changed: - dhcpd can't write pidfile to /run/dhcp-server (and isc-dhcp-server & isc-dhcp-server6 both use the same RuntimeDirectory) + isc-dhcp-server & isc-dhcp-server6 systemd service units use the same RuntimeDirectory leading to loss of pid files -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1543799 Title: isc-dhcp-server & isc-dhcp-server6 systemd service units use the same RuntimeDirectory leading to loss of pid files To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/isc-dhcp/+bug/1543799/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
