[Pdns-users] rec_control wipe-cache not clear packet cache

Good morning to all on the list!
We ran into an oddity with our recursors this morning that I wanted to
consult with you about. There was a domain we knew had it's DNS entries
changed, but our recursors were still getting the old data, and we
wanted to fix that. So, as I always do in this situation, I ran the
rec_control wipe-cache www.domain.com
as I always do in those situations. However, for some odd reason, this
time it did not seem to purge the entry from the cache, because a
subsequent dig query to the recursor still showed the old entry, with
the TTL value counting down. Only by doing a full restart of the
recursor did we actually get the cache to clear.
This was on PowerDNS Recursor version 3.3, using the pdns-recursor-3.3-1
rpms available from the PDNS site.
Question: Is it possible that wipe-cache perhaps does not clear the
packet cache or any other form of entry caching in the recursors?
