I'm observing for a long time next bug: ovn-controller doesn't send DHCPOFFER but it logs that it does. However this VIF doesn't get it at all. But once ovn-controller restarted it successfully seems like it actually send DHCPOFFER and immediately receives DHCPACK from VIF.2025-02-08T14:27:57.462Z|00053|pinctrl(ovn_pinctrl0)|INFO|DHCPOFFER fa:16:3e:80:67:62 13.37.0.5 2025-02-08T14:28:01.746Z|00054|pinctrl(ovn_pinctrl0)|INFO|DHCPOFFER fa:16:3e:80:67:62 13.37.0.5 2025-02-08T14:28:05.582Z|00055|pinctrl(ovn_pinctrl0)|INFO|DHCPOFFER fa:16:3e:80:67:62 13.37.0.5 2025-02-08T14:28:13.053Z|00056|pinctrl(ovn_pinctrl0)|INFO|DHCPOFFER fa:16:3e:80:67:62 13.37.0.5 2025-02-08T14:28:21.972Z|00057|pinctrl(ovn_pinctrl0)|INFO|DHCPOFFER fa:16:3e:84:8e:7f 13.37.0.37 2025-02-08T14:28:25.109Z|00058|pinctrl(ovn_pinctrl0)|INFO|DHCPOFFER fa:16:3e:84:8e:7f 13.37.0.37 2025-02-08T14:28:29.362Z|00059|pinctrl(ovn_pinctrl0)|INFO|DHCPOFFER fa:16:3e:84:8e:7f 13.37.0.37 2025-02-08T14:28:30.003Z|00060|pinctrl(ovn_pinctrl0)|INFO|DHCPOFFER fa:16:3e:80:67:62 13.37.0.5 2025-02-08T14:28:37.820Z|00061|pinctrl(ovn_pinctrl0)|INFO|DHCPOFFER fa:16:3e:84:8e:7f 13.37.0.37 2025-02-08T14:28:38.619Z|00002|fatal_signal(ovn_statctrl2)|WARN|terminating with signal 15 (Terminated) #
