Looking for vaguely plausible causes I guess what might have happened is there was a DNSKEY lookup failure (transient network problem?), so validator.c:fetch_callback_dnskey() returned DNS_R_BROKENCHAIN, so the DNSKEY query was added to the bad cache. After that happens, validation attempts failed for lame-ttl seconds because of the dns_resolver_getbadcache() check in validator.c:view_find().
