Didn't find the time today to browse the logs. the problematic server adc1 logs something after the event in stork. stork displays 2023-06-20 20:01:23 daemon [2] dhcp4 is unreachable kea-debug.log: 2023-06-20 20:00:54.374 CEST INFO [kea-dhcp4.commands/664.140016487107008] COMMAND_RECEIVED Received command 'subnet4-list' 2023-06-20 20:00:54.679 CEST INFO [kea-dhcp4.commands/664.140016487107008] COMMAND_RECEIVED Received command 'ha-heartbeat' 2023-06-20 20:02:04.789 CEST INFO [kea-dhcp4.ha-hooks/664.140016487107008] HA_STATE_TRANSITION server transitions from HOT-STANDBY to WAITING state, partner state is PARTNER-DOWN 2023-06-20 20:02:04.790 CEST INFO [kea-dhcp4.ha-hooks/664.140016487107008] HA_LEASE_UPDATES_DISABLED lease updates will not be sent to the partner while in WAITING state 2023-06-20 20:02:04.790 CEST INFO [kea-dhcp4.ha-hooks/664.140016487107008] HA_LOCAL_DHCP_DISABLE local DHCP service is disabled while the adc1 is in the WAITING state 2023-06-20 20:02:04.790 CEST INFO [kea-dhcp4.ha-hooks/664.140016487107008] HA_STATE_TRANSITION server transitions from WAITING to SYNCING state, partner state is PARTNER-DOWN 2023-06-20 20:02:04.790 CEST INFO [kea-dhcp4.ha-hooks/664.140016487107008] HA_LEASE_UPDATES_DISABLED lease updates will not be sent to the partner while in SYNCING state 2023-06-20 20:02:04.790 CEST INFO [kea-dhcp4.ha-hooks/664.140016487107008] HA_SYNC_START starting lease database synchronization with adc2 2023-06-20 20:02:04.807 CEST INFO [kea-dhcp4.ha-hooks/664.140016487107008] HA_LEASES_SYNC_LEASE_PAGE_RECEIVED received 118 leases from adc2 2023-06-20 20:02:04.809 CEST INFO [kea-dhcp4.ha-hooks/664.140016487107008] HA_SYNC_SUCCESSFUL lease database synchronization with adc2 completed successfully in 19.611 ms 2023-06-20 20:02:04.809 CEST INFO [kea-dhcp4.ha-hooks/664.140016487107008] HA_STATE_TRANSITION server transitions from SYNCING to READY state, partner state is PARTNER-DOWN 2023-06-20 20:02:04.810 CEST INFO [kea-dhcp4.ha-hooks/664.140016487107008] HA_LEASE_UPDATES_DISABLED lease updates will not be sent to the partner while in READY state 2023-06-20 20:06:51.205 CEST INFO [kea-dhcp4.dhcpsrv/664.140016487107008] DHCPSRV_MEMFILE_LFC_START starting Lease File Cleanup 2023-06-20 20:06:51.206 CEST INFO [kea-dhcp4.dhcpsrv/664.140016487107008] DHCPSRV_MEMFILE_LFC_EXECUTE executing Lease File Cleanup using: /usr/sbin/kea-lfc -4 -x /var/lib/kea/dhcp4.leases.2 -i /var/lib/kea/dhcp4.leases.1 -o /var/lib/kea/dhcp4.leases.output -f /var/lib/kea/dhcp4.leases.completed -p /var/lib/kea/dhcp4.leases.pid -c ignored-path 2023-06-20 21:06:52.202 CEST INFO [kea-dhcp4.dhcpsrv/664.140016487107008] DHCPSRV_MEMFILE_LFC_START starting Lease File Cleanup 2023-06-20 21:06:52.203 CEST INFO [kea-dhcp4.dhcpsrv/664.140016487107008] DHCPSRV_MEMFILE_LFC_EXECUTE executing Lease File Cleanup using: /usr/sbin/kea-lfc -4 -x /var/lib/kea/dhcp4.leases.2 -i /var/lib/kea/dhcp4.leases.1 -o /var/lib/kea/dhcp4.leases.output -f /var/lib/kea/dhcp4.leases.completed -p /var/lib/kea/dhcp4.leases.pid -c ignored-path 2023-06-20 22:06:52.466 CEST INFO [kea-dhcp4.dhcpsrv/664.140016487107008] DHCPSRV_MEMFILE_LFC_START starting Lease File Cleanup 2023-06-20 22:06:52.467 CEST INFO [kea-dhcp4.dhcpsrv/664.140016487107008] DHCPSRV_MEMFILE_LFC_EXECUTE executing Lease File Cleanup using: /usr/sbin/kea-lfc -4 -x /var/lib/kea/dhcp4.leases.2 -i /var/lib/kea/dhcp4.leases.1 -o /var/lib/kea/dhcp4.leases.output -f /var/lib/kea/dhcp4.leases.completed -p /var/lib/kea/dhcp4.leases.pid -c ignored-path 2023-06-20 23:06:53.457 CEST INFO [kea-dhcp4.dhcpsrv/664.140016487107008] DHCPSRV_MEMFILE_LFC_START starting Lease File Cleanup The other server only says: 2023-06-20 20:01:04.701 CEST WARN [kea-dhcp4.ha-hooks/291908.140125778662080] HA_HEARTBEAT_FAILED heartbeat to adc1 (http://10.0.0.231:8000/) failed: unable to forward command to the dhcp4 service: No such file or directory.
