I think the problem is that if you do a :
dig +multi @dnssecserver thedomain.thetld dnskey +dnssec | grep 44526
You then see still that key id exists in DNSKEY records (and an RRSIG of
that ZSK, the 44526, but outdated!!!!).
But I don't really understand why because you see the delete date of
44526 is very old....
Anyway that could explain the error : "dns_dnssec_keylistfromrdataset:
error reading .........private: File not found", because it seems Bind
source code, checks the DNSKEY and later tries to load that keys. As the
files for keyid 44526 don't exist, that could (are renamed) that could
explain the error.
But why has this happened??. Sometime ago, it happened to me that in
this machine (it's more than nothing a learning machine), the ZSK got
outdated because the script in charge of renewing the zsk was stopped.
So the only supposed valid key could have been in that moment the KSK
(which does not get expired). Could perhaps, those ZSK become
everlasting or similar, although in the file the date sais it's totally
outdated....
I can't understand what's happening there...
