The discovery made throughout this entire bug is that DHCP failover code is entirely broken in all versions of ISC dhcp except 4.1.0 and higher. So the hotfix package built for this issue has dhcp-4.1.0 built and installed alongside the existing version of ISC dhcp. As stated by mosvald, the customer did verify that dhcp-4.1.0 solved the problem for them and the hotfix package does provide the right executables, so we just need to verify that they are using them: 1) Is the hotfix package installed on all affected systems? 2) Have they modified /etc/init.d/dhcpd to use /usr/sbin/dhcpd4? 3) They should chmod 0000 /usr/sbin/dhcpd just for safe measure. Aside from that, I have no ideas. The only real solution is to have this customer use dhcp-4.1.0. That's been provided in the hotfix, but they have to manually edit the dhcpd init script and make sure they are using the dhcpd4 binary over the dhcpd binary. Development Management has reviewed and declined this request. You may appeal this decision by reopening this request. |
