[Kea-users] ALLOC_ENGINE_V6_ALLOC_NO_LEASES_HR and ALLOC_ENGINE_V6_ALLOC_UNRESERVED

[Veronique Lefebure]

Hi,
Out test client is failing to get an IPv6 IP.
Enabling debug logs, we see messages from the server that seem contradictory:

2022-06-21 16:43:50.948 DEBUG [kea-dhcp6.alloc-engine/13499.139838611867840] ALLOC_ENGINE_V6_ALLOC_NO_LEASES_HR no leases found but reservations exist for client duid=[00:01:00:01:2a:44:7a:5c:xx:xx:xx:xx:xx:xx], tid=0x93e611 2022-06-21 16:43:50.948 DEBUG [kea-dhcp6.alloc-engine/13499.139838611867840] ALLOC_ENGINE_V6_ALLOC_UNRESERVED no static reservations available - trying to dynamically allocate leases for client duid=[00:01:00:01:2a:44:7a:5c:xx:xx:xx:xx:xx:xx], tid=0x93e611

where xx:xx:xx:xx:xx:xx is the client mac address.
How can that happen ?

Kea has correctly identified the subnet where the client reservation is defined:
2022-06-21 16:43:50.947 DEBUG [kea-dhcp6.packets/13499.139838611867840] DHCP6_SUBNET_SELECTED duid=[00:01:00:01:2a:44:7a:5c:xx:xx:xx:xx:xx:xx], tid=0x93e611: the subnet with ID 2156789248 was selected for client assignments

Thanks for helping.
