[Kea-users] Lease Database ALLOC Error

[Jeronimo]

Hi,

I am trying to configure lease-database with a Postgres SGBD. The Kea
server start and alloc addresses but after a time these errors begins

I can see the lease in the Postgres DB:

*address,duid,valid_lifetime,expire,subnet_id,pref_lifetime,lease_type,iaid,prefix_len,fqdn_fwd,fqdn_rev,hostname,state,hwaddr,hwtype,hwaddr_source,user_context2001:db8:706:801::5,"{""type"":""Buffer"",""data"":[0,4,170,146,128,6,66,205,110,159,203,167,171,27,180,36,20,101]}",400,2021-05-04T06:16:13.000Z,1,300,0,-1252104193,128,,,ubuntu20.,0,"{""type"":""Buffer"",""data"":[]}",0,0,*

Reestart the Kea Server does not correct the issue.
I need to truncate lease6 table to correct the operation of the dhcp6
service.
Well, seems that Kea can't locate and update/erase the lease in DB. But why?

Anyone can help me with any ideia?

Thanks in advance.
